Giro Aerohead
Quote | Reply
Okay, not that it's official, I can tell you my thoughts and experiences with the new Aerohead.

First, Giro is actually being pretty conservative with it's time savings estimates, but that's not the story I think needs to be told. In my opinion, there are a few points which should be of greatest interest to all of you...

  1. While I haven't conducted all the aero testing, I do know our results and the results of the tunnel tests, and will say the most remarkable thing about the helmet is it has tested as the fastest helmet for every athlete that I know of except one, and even for that athlete it was a wash against the LG P09. I don't know the total number of those who've tested with it, but I do know it's more than just a handful. We have never seen a helmet work so well for everyone who's tried it. It really becomes the new helmet for, if you can't test, its the safest bet.
  2. The fact that the shield covers the ears instead of tight flaps means that T1 (and T2 for removal) will be easier. This may seem like a small point, but I believe it's important. There's no pulling this helmet around your ears and on to your head. You simply put it on and go. Easy peezy.
  3. Working off of point 2, because the ears aren't covered with flaps you can hear what's going on around you very well. This is a nice safety feature. I don't know if it was intended, but it works well in this manner nonetheless.
  4. I'm shocked at the $250 option. Honestly, I would be charging you geeks a lot more than that! To be completely honest, and to risk you all getting angry with me, I was asked for my opinion on this and suggested a price of $350 - $400 would be reasonable. Kudos to Giro for not listening to me.
  5. Given at least a tiny peak inside the design process, I was surprised at the time and energy spent on the shield(s). Honestly, this was the bulk of our testing since last year. You want to know why it's taken so long to bring this to market? They were adamant in getting the shield just right. Let me give you an example. During testing with Rohan Dennis, there was actually one shield that tested faster in the wind tunnel than all the others. Problem was, once testing was done with us, it became quite clear it was a non-starter because he simply couldn't see when he was actually riding his bike. Again, I was only privy to a very small part of this helmet's development, but we tested a bunch of shields.
This was the first time I worked with Giro, but my experience resulted in a new found respect for the company. This rings true for pretty much every company I've worked with. These guys really want to put out a great product, and worked hard to do so.


I'll try to answer questions, but I have a pretty busy schedule over the next several days.



Edit: Sorry for the first incomplete post. I just learned not to post to this forum using an IPad.

Jim, what were you seeing in time differences between the standard and Ultimate versions?

Has anyone seen an official release date? VN says "Fall" and Aerogeeks says "Summer". An actual date would be great.....

The numbers Aerogeeks is reporting come from our testing and tunnel testing, so that's the easy answer.

Again, I have to give credit to Giro, they're not reporting "pie in the sky" numbers. I actually expect most people will see greater time savings than they're quoting, but they've chosen to be conservative and I respect that. For that reason, I can't really give you any other numbers.

I did forget one thing from my original post. Aerogeeks also quoted 15 watts over the Advantage 2. That number is absolutely correct, but there's more to the story. Rohan really liked the A2 and wanted it to test faster. This is always dangerous for us because when an athlete wants something to test faster, they'll sometimes give a little extra shrug or do something else to "help" the product, whatever it may be, to test better. I'll be honest, the guys from Giro didn't want him to test the A2, and it was the last test we did on that particular day. Let me tell you, there was a big sigh of relief when it immediately became clear the Aerohead was crushing the A2 and, when Rohan completed his run, he stopped and smiled knowing full well it was slower before we ever gave him the results. He could feel it. Just a little behind the scenes info for all of you.

would you have info on how each of these two new helmets ventilation system will perform in very hot ironman races? From first look those helmets don't seem to provide a lot of ventilation, the $250 helmet seems to be better than the $550 in that regards, and the time savings comparison between the two helmets are not very different.

Thanks in advance for your feedback!

How does the helmet test sans visor? The visor looks a lot more integral to the aerodynamics (ear coverage, etc.) than with other aero lids.

Now I am upset. I wanted this helmet, but then saw the $550 price tag, so I then planned to just buy the specialized TT helmet which is available now and I get at a reasonable price. Now they also release a $250 version! That just messes up my plans and now I need to wait for this stupid thing.

According to piece on Lava, if you ditch the shield and use glasses the "drawback isn't that much". Of course, I'd trust Jim's word more than a marketing piece form Giro.

I'm interested in this helmet but I had really bad experiences with the AA shield so I'm more interested in how the shield on this one handles fog and sweat.

Thanks for the info Jim! Curious if it can beat my old Vorttice (which as you know tests as well as anything currently available for me).

I always wonder what takes them so long to get these things to market. Would have thought they would release it in spring, or at least during the TdF, for max impact. By Aug/Sept/Oct, many people will be largely done racing for the year and then will wait until 2017 to buy a new helmet. And by then there are likely to be other new options to compete with.

Exactly. If the screen is such a large part of the aerodynamics, how is it w/o the screen? I saw several riders ripping that screen off during the TT of the Giro in the rain. How does the helmet compare to the Specialized (that is neutral with or w/o screen).

ERO doesn't do weighted yaw. It's velodrome testing so basically 0deg with maybe a little bit of off zero thrown in in the corners and for an imperfect line.

Have you raced at Carson?

I get blown around there quite a bit at times with a front 808 or front disc. It's definitely not zero at times.

I think for ERO testing though they're more careful about shutting down some doors known to be related to some of the stronger drafts.

In any case, Jeffp was talking about the Giro-reported data, not ERO's.

Where is the technical aerodynamic breakthrough here? The shell portion of the helmet looks pretty unremarkable except for its overall size. Is the spiting of helmet into an upper and lower half the breakthrough? This allows the lower half and visor to be a continuous section?

I'll try to answer some of these questions, but the specific numbers belong to Giro, and are their's to make public.

  1. Shield or No Shield - I don't have the numbers in front of me, and we didn't test anything that went over the ears if you should choose to use sunglasses instead of the shield, but I would definitely use the helmet with the shield. I think Giro has mastered using a shield to "complete" the airfoil shape, which is why their helmets test faster with a shield than without. Plus, it's amazing how many people lift their heads to see under the frames of their sunglasses when out on the road, effectively raising their CdA.
  2. Position Influence & Design Breakthrough - I'm not exactly sure why this helmet works for so many people, but it doesn't seem to care about your position. I think it's partly due to some of the length being up front instead of using a longer tail. The "brow" of the helmet is more in front of you, so perhaps that negates the influence of the athlete's shoulders and back? It's also a very narrow helmet when seen from the front, though no one complained it was too narrow for their head.
  3. Shield Attachment - The magnets on this helmet are far stronger than previous helmets. The shield practically jumps off your hands when you put it in place. Keep in mind, I've only tested prototypes, the last one being two weeks ago.

Something is off...
15W yields ~1.5s/km, your testing indicates 5.5s/40km, or 0.14s/km, an order of magnitude less than the WT claims.

Has someone blown the WAD out of proportion?
The 16grams between A2 and Selector is ~2W, not 10w as claimed.

What am I missing?

That's 10W at 50kph. The savings is roughly 1/2 that at 40kph, and 1/5 that at 30kph......it's not like the guy putting out 450W and the guy putting out 200W both save 10W.

Anyone care to break down the fine print for me on the Giro time/drag savings chart here: http://www.giro.com/...tm_campaign=homepage

I wouldn't come anywhere near putting out 400 watts over 40k, so how do I scale this to my own FTP? Could I use the wind average drag data deltas to equate it to my typical average power output and speed?

Also, is the baseline the original Advantage or the Advantage 2 helmet?

Best,

The website states the Ultimate features a TeXtreme carbon fiber shell – a stronger, stiffer material provides a slimmer shape with less frontal area. So is it actually narrower than the regular MIPS? Do you have any photos showing this?

hmmm....

so here is another (possibly stupid) question. is a watt a watt a watt.. meaning.

assuming i ride 35kmp, it would be assumed that i would save 2.5 watts (roughly) with this helmet over the rudy project helmet.

2.5 watts might not seem like a lot for someone who's ftp is 250, but my ftp is about 200, seems like a 1% gain. assuming this, this 2.5 watts should go further for someone like me, who only weighs about 122lbs on race day, thus increasing my w/kg ratio higher than it would be for someone weighing 160lbs..

meaning, the helmet should have a more drastic effect for someone like me?

the watts for the rider listed are really a red herring. if the helmet reduces drag by X amount at Y speed, the things that are relevant are the X and the Y, not the Z power output as the rest of the rider/bike system might be assumed to remain unchanged. Give that the number posted make no sense on the Giro site, ie 1g reduction = 1w means they either need to correct their data or tel us why they are testing at 50 mph instead of 30mph(or whatever speed they are testing at , as it is not listed on the site) While Jim may be giving good insight, the giro site really looks like bad marketing spin that was not checked before uploading to the interwebs

It is not easy, but not impossible. The six magnets are quite strong. I would say it would be more difficult to remove the visor from the top of the helmet to use it again than to initially take it off.

There REALLY needs to be an insistence on drag values and differences being reported in terms of CdA (and in m^2...I'm looking at YOU, A2). They can still do all of the calculations for time and power for various speeds, but at least report the most universally useful value. It's not that hard :-/

I agree there needs to be a standard reporting metric. And I agree with the way you want to do it. On the other hand asking marketing people and the average athlete to comprehend drag in M^2 units is a pretty big ask. I am actually impressed with how well most companies' marketing depts are getting at reporting this data responsibly, even if it is in force (grams).

And in response to your comment about A2, as long as A2 is owned by Aerodyne, and is located in the greater Charlotte area the units will be in imperial. I know plenty of aerodynamicists that spend countless hours at Aerodyne that would be fine with metric units, but the people that they are producing data for would pretty much go sideways if information was presented to them in metric. And they more than occasionally attend tests, so the data has to be in imperial. As is usually the case, follow the money.

The other major difference is the shell material: the Aerohead Ulimate MIPS uses TeXtreme carbon fiber while the Aerohead uses the traditional plastic. The use of TeXtreme allows Giro to reduce the frontal area by 2%.
(Cyclingnews)

I'd be curious to know the technical reason that TeXtreme allows the 2% reduction in frontal area. I'd assume it has something to do with passing a Snell test (or whatever the certifying test is) since I think the plastic cover has basically no significant stress on it except in crashes? And I'd thought that carbon fiber isn't that great at handling the kinds of impacts you'd expect in a crash.

The cynic in me suspects it could be just a way to justify a higher margin on a premium helmet.

I don't know, but I suspect that the textreme allows the impact force to spread over a larger area of foam....thereby needing less to pass the test.

That's why I said that it's still ok to "translate" into typical watts, typical time savings, etc. but at least provide the CdA values since those "typical" values require specific assumptions (that tend not to be specified).

The units thing is funny and really isn't a big deal IF the people using the non-standard units actually list them. I looked at a recent A2 output and the fact that they didn't label the units on the CdA column was causing some confusion. In any case, what's the big deal about using m^2 anyway? They already list the balance reading in grams and calculate the power estimates in watts :-/ Besides, the units on the CdA value don't just represent area, but actually "drag area" which most people really don't have an intuitive feel for anyway, so it's really just a scaling number. Not reporting in m^2 for their cycling equipment tests is just being lazy. It's not the raw output, but a standardized calculated value. Just change the danged cycling test spreadsheet, no?

That is probably what I am most interested in for this helmet and the drag data with the shield on top. That or the capability of the shield to shed water. For some reason, most of my events have either some rain or heavy mist and I have to lift the visor of my current helmet in order to see. After things dry out a bit it is very easy to put back down.

"At the track, Giro found the Aerohead saved 15 watts when compared to the Advantage (nine watts versus the Air Attack Shield), and the Ultimate saved an additional two watts."
I'm betting this is in fact what Jim measured. Jim's testing would have been on the track so probably 25-30mph range, though I'm not 100% sure what speed the watts difference is calculated at. Whether we believe it's truly this large a difference on average across different riders is another question. Also noone ever seems to want to report standard errors, but I suppose we have to get them to report units first (preferably CdA) and work on s.e.'s later!

Regarding the shield. How difficult would it be to take shield off and attach on top of helmet while riding? I'm thinking if it starts to rain and I need to remove the shield.

They showed this helmet on this week's GCN show...specifically removing the visor and snapping it higher up and upside down.

I also found it odd that the CF-shell helmet would weigh the same. Density of the CF is ~1.8 vs PC at ~1.2. You should be able to produce a thinner shell and get equivalent or greater stiffness from the composite shell. They also chose to play with the geometry. So a bit tough to say for sure - just unlikely that it all shakes out at the same weight.

The other thing to consider, is that the Ultimate is solid while the base Aerohead is vented, so that may account for that difference as well. I have only been able to test the Aerohead.

One of the problems of all this folk lore is it's hard to collect and verify. I've talked to Jim extensively and tested the Advantage on the track versus maybe 6-8 other helmets, and I never heard Jim say that, and certainly didn't find that myself, but that doesn't mean it isn't what other people found. My experience has been that the newer helmets have generally been better than the Advantage, but that many of them are about the same as each other (for me). I thought that Jim was a fan of the Specialized, but I might not be remembering right.

I've never seen the salad bowl test better. I've seen a few tested too. Again it is rider dependant.

The A2 has been, probably 95% of the time, in the top three of all tested helmets. It is rarely the fastest helmet. The Selector is pretty good overall as well.

My intel on the new AeroHead has been the same. It has been the best for everyone that has tested. Hopefully I'll personally get back into A2 Wind Tunnel and give it a whirl soon. All my time there lately has been from the outside looking in.

Anyone care to break down the fine print for me on the Giro time/drag savings chart here: http://www.giro.com/...tm_campaign=homepage

I wouldn't come anywhere near putting out 400 watts over 40k, so how do I scale this to my own FTP? Could I use the wind average drag data deltas to equate it to my typical average power output and speed?

Also, is the baseline the original Advantage or the Advantage 2 helmet?

You ordered thru this Bike Helmets Direct one? Did you choose next day shipping? Link says not expected until the 13-14th, or maybe you just got geographically lucky. Fwiw, I ordered mine thru the Giro site, although I wish I could have done the Amazon as the Discover IT card, currently has 5% quarterly savings at Amazon, plus mine gets doubled for first year. Regardless, I paid for next day, hopefully get it tomorrow so I can use it maybe for a race on Sunday. Got shipping confirmation this morning.

My take is it would be because it doesn't have the vents like the cheaper version. Jim Manton can certainly chime in and comment but that's my understanding.

were is Jim when we need him!....... Been in with S-works now for 2 years and has no vents i seem to have survived racing in Galveston and Buffalo Springs, despite the sweat that was pouring down my visor. Would love to know if its 15 sec or 2min difference. Your right at 15 would rather save the 300$ at 1min i would rather spend the 300$.

Giro has aero data on the site. 1 second savings for 40K at 400 watts, and 5 seconds savings for 180K at 250 watts. Not sure who rides 40K at 400 watts so maybe 2 seconds savings for us mere mortals.

$300 for maybe 3 seconds savings for a 70.3 is not worth it at all. Especially when it's 10% warmer of a helmet.

I rarely do TTs and so rarely wear my P09 TT helmet, but I know it runs a lot hotter than my Giro Synthe road helmet. I wouldn't race a TT in my Synthe, but I don't think CdA is the only determinant of what makes a "fast" TT helmet.

Much like with tires, we have to look at both Crr and CdA, and we've now come to the view that generally speaking, running 23mm tires makes more sense than running 18mm tires (the decreased Crr of the 23mm tire more than makes up for the increased CdA of the 18mm tire).

I've got to think that TT helmets are the same, in that you have to balance CdA with ventilation, especially as you consider increased distances, warm weather races or simply your individual propensity to overheat.

There are studies showing that when the body overheats, power can be significantly affected. So the question is, yes a helmet with limited ventilation may have lower CdA, but how much does it contribute to your core temperature rising and the resulting loss of power.

Initial impressions are of excitement of course, overall look and feel is very nice. Feels light, I was expecting TT helmet to be a bit heavier. The magnets are strong, like they snap in and off. There are indentations for where they sit when in the normal visor position and when you flip it upside down and up it's pretty easy to get it right where it needs to be and it grabs it. Visor is very visible and in aero position the top isn't blocking any view, better than glasses as no frames on the side to interfere as well.
For fit, I am right at the top of the M size (which what I got) and it I think it fits snug. Really secure on me, my head shape is more of a round oval (based on motorbike helmets).
With the shield on my ears just touch the visor, so for me in a T1 situation I'd have the visor on the top and snap down after. When sitting on the bike my nose just touches the bridge, but this is all static so I'm sure will take time to adjust and find the right placement.
When just wearing the helmet it does seem hot, I could feel it catching heat but of course that's standing still.

That's it so far I guess.

There REALLY needs to be an insistence on drag values and differences being reported in terms of CdA (and in m^2...I'm looking at YOU, A2). They can still do all of the calculations for time and power for various speeds, but at least report the most universally useful value. It's not that hard :-/

Aero improvements will probably save you more time if you are going slower, but it won't be a huge difference. Not like the dreaded "watts saved" numbers and other measures that are commonly used.

A2 does m^2 now. Well at least when we are there for AeroCamp. I asked them to add that to the spreadsheet for us. I'm not sure if everyone get's that spreadsheet, but it is available if you ask.

It gets confusing in there sometimes since we often talk to the athletes in watts since that is easily understandable. In the control room we talk to each other in CdA, except when we are looking at speed adjusted watts so we can relay that to person being tested.

Your initial impression and fit is almost exactly the same as mine. My noggin must be a little higher as the shield does not touch my nose. My three year old says it looks fast so that's worth a few extra watts, lol.
I also ordered a large, but it felt too loose. The shield also touched my cheeks in certain positions. Rather than returning it, I have it up for sale in the classifieds if anyone is interested.

In terms of sizing, I currently race in a Giro A2 in large and my every-day helmet is a Evade in medium. I'm thinking that since I wear a large with the A2 the Aerohead would probably fit best in a large.

I do have a little room in the Evade, but not that much.

I brought mine to the UW tunnel on saturday.
We had 13 helmets on hand, but the other two people had small/medium sized heads and brought helmets accordingly. My large melon meant I didn't get to sample as many as I'd like.

The data they provided is not so friendly as cda, so numbers will have to wait. I did find the aerohead tested better for me than my old javelin (large) and kask bambino (medium). I couldn't squeeze into the Cateye, Poc, or lazer wasp.

The aerohead did NOT test better on the other riders, but perhaps if we had a medium (or even small) on hand, that may have made a difference.

No. Just no.

This helmet will be fastest for some, but not everyone. I have tested loads of helmets and the 'fastest' for me has changed 3 times do to other minor positional tweaks. I'll test the Aerohead in a few months, but I'm not holding my breath for a drop in CdA.

Sure, you could say that it's because the helmet was too big for those other rides, but this just illustrates another problem with absolutes. I can't fit into a medium Selector, but I can fit a medium Javelin, Cerebral, and Split. Guess which of those four is consistently slowest on me? Just because A is faster than B on subject X, does not mean it's fastest if C through Z haven't been tested. Is the Aerohead a good shout in a vacuum? Dunno, could be the next P09 or S-Works. It could also be the next Bambino...

There's also the issue that it's near-impossible to make it a blind test.

Jim@ERO was giving people a special double-secret unreleased helmet to test. Sometimes that makes you feel special, and you want it to be fast, so you hold your position a little better, etc.

Yep and I believe even Jim was the one that said iit is very dangerous when a rider wants something to test fast. You could make the same argument for Jim as well, it is dangerous if he wants it to test fast. As for the UW test, yes you definitely can't test a large on people that can fit into a small or medium.

I brought mine to the UW tunnel on saturday.
We had 13 helmets on hand, but the other two people had small/medium sized heads and brought helmets accordingly. My large melon meant I didn't get to sample as many as I'd like.

I did find the aerohead tested better for me than my old javelin (large) and kask bambino (medium). I couldn't squeeze into the Cateye, Poc, or lazer wasp.

The aerohead did NOT test better on the other riders, but perhaps if we had a medium (or even small) on hand, that may have made a difference.

Also looking through all the pictures from the windtunnel test, Dan's back silhouette is very different from the other 2 riders that we tested. Therefore it might be safe to say that a "fast" helmet might give you a good drag number but it might not be your smallest drag number. POC and Lazer tested very fast for the other testers (while the aerohead did not), but unfortunately Dan could not fit into those, so we will never know and the aerohead available was way too large for one of the other testers.

I guess, if you want to know... come to the tunnel with us. We are planning another set of windtunnel-days in the fall/winter in Seattle (the rest of the summer is booked with air craft testing). Cost approx. 700$ for a minimum of 2h of testing. We only test 3 people per 9 hours (day), so we have plenty of testing time to get your curiosity satisfied. Send me a message and I will keep you in the loop.

For those that have received their helmets, what is the plastic lining on the inside of the helmet? It is below the padding and has tabs that attaches it. At first I thought it was just part of the packaging but after looking at it, it looks like it is suppose to be there. It seems like it would restrict air flow inside the helmet and make it hot.
Thx

Ok, here's my offically unoffical review after my first ride with the Aerohead.....

Overall, a very positive experience. Definitely seems to be an improvement over my Bambino, at least in terms of speed (yes, that is completely subjective...no data to back it up). A few points:
  • I did have some vision block when I was on my extensions. Was kinda surprised by this given the large visor, but I think it is because there is a large section of helmet that comes out from your forehead. I also ride pretty low, so that doesn't help.
  • A bit heavy....seemed noticeable to me. Wondering how it will feel after 112 miles.I normally don't do long rides with my race helmet, but may do some with this helmet just to get used to the weight.
  • Decent ventilation, not great. On the highly-sensitive and un-calibrated P13 PSL Scale (Perceived Sweat Level), it is better than my Selector, but worse than my Bambino. But it was fairly warm and humid today (high-80's, I think).
  • No rumble sound. The lack of ear flaps means you can hear more of what is around you without that annoying low-rumble you get from most aero lids.

Only rode for about an hour today......I'll be wearing the Aerohead on Sunday @ Racine. Supposed to be pretty warm (mid-high 80's)....we'll see how it performs then, but based on this initial ride, I am pretty excited about it.

In the wind tunnel, I tested faster with it cocked back a bit. Instead of the nose bridge sitting ~1cm off my nose, it was better with it pulled back another 1-2 cm. That would also have the benefit of pulling that forehead bump out of the sightline. I have not ridden it out on the road, where it actually matters if you can see ahead, but in the tunnel, I did not notice any problems with reduced vision.


(of course, no guarantee that rotating it back is also better for you, just food for thought)

Yeah, I loosened the retention device and rotated it back on my head a bit, but it always came back forward. Dunno how I will wear it on Sunday....game time decision I guess.And the vision block wasn't huge, but enough that I couldn't just rely on looking up with my eyes all the time....had to lift my head a bit as well. Again, I ride low and usually head down, so that isn't helping.

This was the MIPS version, not the Ultimate.

if you adjust straps with it back it should mostly stay. it seems to have a bit of built in rock as part of the mips system

also, the magnets seem fragile, ie I had to reassemble one after just taking visor off anon about 5x. it feel apart into the 3 distinct pieces. hopefully it will stay together.

Took mine out for a 75 mile ride today. It was a little hotter than my Giro Attack Shield, however I could certainly feel air flowing through over the top of my head. Comfort and fit was about the same. Shield is much better along with the magnets being way stronger.

As for speed...well I KOM a 11:56 segment by 0:06 seconds that I've been chasing for a while. I'm going with "the helmet made the difference" to help justify the needless purchase;-)

Do you have any feel on how much drag difference there is between a medium and a large? On me a medium is a tad bit tight - 2 pressure spots on the back of my head that feel like no big deal, but after a few hours they might be bad... have to have the harness extended all the way to get it on my head. The large is very comfy, but looks really big on my noggin.

To be honest, no idea. I was going to test a small vs a medium last week for an Olympian, but the small was just too small and unrealistic for him, so I didn't get the numbers. Chalk up another win for the Aerohead, though...it outclassed the Specialized S-Works TT helmet pretty handily for that athlete. I suspect you'll see a lot of them in Rio if federations can get their hands on them.

Any thoughts on getting the Aerohead on your head quickly in T1, anyone? It looks like there is not so much room to quickly squeeze your head past the visor when it's mounted, but cannot really tell without trying it in person... are you supposed to install the shield/ align the magnets after you have the helmet on your head? Or is there enough room to get it on your head with the visor already correctly in place? I have a P-09 currently and the visor is pretty easy to flip up and down. Thanks.

I previously used the P09 before and Aerohead for the first time this weekend in a race. Updated my original post with my new findings about using it in a race. See the bottom of the page if you already read:

Looking at the time savings quoted by Giro, their baseline is the Advantage. I thought that the Advantage was faster than the attack/shield by a decent margin. Is this not true? I currently race in the Advantage2, but am considering the Aerohead for my upcoming A race in August.

Depends on the rider. To say that the Aerohead is faster for everyone is disingenuous, and to say the Attack is generally faster than the Advantage contradicts the data I've seen.

To be perfectly clear, I have never used the P-09 with face mask so I can't compare that aspect. The Giro Aerohead, does not look remotely aero with the shield removed. With that being said, the Giro Aerohead is significantly hotter. I am slightly worried about it at Racine this weekend. FWIW, I set a monster PR last weekend. I am sure a big part of that was the change this year to the GIRO SLX with elastic laces, a tighter fitting skinsuit, and the Aerohead.

It is funny, but probably the most surprisingly thing about the wind tunnel was the perceived hotness of various helmets I tested. At that speed with that wind it really makes a difference. I started with a P09 and I was very comfortable, then I started testing other helmets, Kask Bambino, Catlike, POC, etc and it was amazing that I could actually feel the heat. The P09 is clearly a very well ventilated helmet for my head.

If you are on the fence, I did notice that Amazon now has a listing where they handle the logistics and is Prime eligible. You could always buy one, check it out, and see if it may or may not work for you. As I listed in my write-up, the shield detaching in my first race with it was downer. And I think it is important for everyone to take a look at the visor. The shape does have some optics tilt/shift to it from I presume the unique shape of it. I have very good eyes but it may be a problem for those with issues.

It was actually at 5pm and it was a chilly day so the later and later it was getting colder and colder outside and the tunnel had been running all day as it was part of wind tunnel camp. I also went back to the P09 as it was the fastest so after helmet testing we went back to it. Given all that there is no way it wasn't the result of the helmet itself. The P09 is a very cool helmet on my head.

I called Giro a few days ago, and followed up again today. (800) 456-2355 (option #4)
Gave them my name, phone, and email.

They said they are aware of the CPSC issue, and they are currently looking into it and will come back with a response in a day or two.

Do you think I should even try to race with the Aerohead this Sunday?
Right now, I'm planning to bring 2 helmets into transition, and fall back to my other one if the Aerohead is rejected by an official. Can you be DQ'd after the fact if you race with it, and its later discovered to be missing the CPSC sticker? Is it even worth trying?

On another note, I plan to do some Chung VE testing loops tomorrow and see if I can get some aero data on the new helmet.

Good to know, let me know if they come back with a response, if not I'll call them in the next couple days if I can find time.

I'm planning the same thing, to bring my old helmet as well as the Aerohead for next weekend and if they don't check (they almost never do knock on wood) just roll with it. I'm not sure if you can be DQ'd retroactively. If any USAT officials are reading this those last two sentences were a complete joke and I follow all the rules 100% of the time, now if you'll excuse you I'm gonna finish my run up Mont Ventoux.

Did a few test runs with the Aerohead. Very comfortable. First time using a helmet with a visor, and I love it. Clarity is great. No more sunglass frames obstructing my vision.

I've only recently started attempting Aero testing using Chung VE method, so not that proficient. This morning's test gave mixed results, so I can't draw any hard conclusions. The first few tests looked promising, as CdA appeared to be lower for each successive test as I first tested a regular road helmet(baseline), then my current GRAY Aero helmet (-0.0020 CdA), and then 2 runs with the Aerohead (-0.0097 & -0.0078 CdA).

But, when I then went back to re-test the baseline, and the GRAY, they both tested significantly better than the earlier tests, even beating out the Aerohead tests.

I need to refine my testing protocol. Next time, I'll do a bunch of runs only swapping between 2 helmets, and see if I can get more consistent and discernible results.

Well, I am pretty sure that it is not legal to sell non-CPSC bike helmets in the US in the first place. That is why helmets like the specialized-mclaren were not sold in the US.

It's not as bad as you're thinking here. They are different certifications, but helmets can and often do meet both requirements (there are some helmets that will only meet one standard though). The aerohead does, it's just that some don't have the physical sticker inside the helmet.

That is true for some helmets, for example the S-works TT helmet, but it is not true for all helmets.

I looked up the rule recently on both the USAT and WTC websites and they clearly state that the CPSC sticker is required.

Yeah I know most helmets meet both, I thought I had read that somewhere but haven't been able to find it since so I was probably tripping balls imagining things

If people can see you from the front you're not aero enough.

It's been a week now since I brought this up with Giro and they still have no solution. They say they are working on it. I am starting to worry that the problem is bigger than they just forgot to put the sticker on....
I honestly can't imagine a scenario where a Giro helmet ends up hitting the market in the US without having passed CPSC. So that leaves two possible scenarios: (1) they forgot the sticker, (2) there are two different versions and they mistakenly shipped the CE one out to some US customers. I'm still betting it's (1), because if it were (2) I wouldn't think there would be two logos on the US box. Regardless, they will surely be legally required to fix the situation so nothing really to worry about. Also I'm confident the helmet is as safe as anything else so this is really just a labeling issue.

I'm sure they will fix it, but I have IM Boulder in just over 2 weeks... So I would really like it solved in time for that.

And it looks like a solution has been found - despite them originally saying that they could not mail me a sticker to put on the helmet myself:

We are waiting on the stickers to get here, we will overnight them to you if it gets close to August 7th.

Also I called per earlier messages and they said "they have my contact information from my email and they will let me know" (in a nice tone)


Rep stated they had no fix and no ETA. Kinda bummed they are all over the place on what they are telling people. It is a sweet helmet and I was planning on using it at Toughman as a part of a relay. Still might roll the dice and hope that they don't check the helmet for the sticker and will bring a back up just in case.

Hi Slowtwitch,

It’s really great that so many of you already have an Aerohead and that you’re loving this new helmet. We’re really proud of it, and we’re eager to see more of you racing in it. However, we’re so sorry that the CPSC sticker issue is getting in the way right now!

As many of you already know, the Aerohead MIPS is dual-certified to both the European EN1078 and the American CPSC helmet standards. Unfortunately, the first shipment of Aerohead MIPS helmets arrived with only the EN certification labels. These helmets are fully compliant with the performance requirements of the CPSC, and although there was an error that resulted in the certification label missing from a few dozen helmets, the important warning labels are present and the helmet still meets all the performance requirements for CPSC.

We’re here to help sort this out. We’re printing stickers as quickly as possible, and we’ll send you a sticker via overnight shipping. Simply call us at 1-800-456-2355 with your proof of purchase, and we’ll send the necessary labels.

Thanks!
Giro Sport Design

Thank you for the update.

Just called the number to request a sticker, and was informed that they are still waiting for a resolution and will contact me once they have one. I mentioned the specifics of this post, and was again told that I will be contacted once there is a resolution.

Ok then.

I'm thinking of borrowing the sticker from one of my old helmets in the meantime.

I left my name and number at that 800 number yesterday, and got a call back today from a rep named Steve. They are not certain that they can overnight the CPSC sticker for me to receive it in Whistler tomorrow for Sunday's race, but he's going to try. Apparently the stickers are first being sent to California. I don't think anyone has ever checked my helmet at a race anyway (famous last words!)

Hmm - sorry about that. We will be receiving the stickers at Giro's headquarters here in California before 3:30pm today, and we're planning to ship them out via overnight shipping for Saturday delivery. If you need this sticker for a race this weekend, please contact our customer service ASAP to make sure you're on the list.

If you have any issues/concerns (or don't feel like customer service really got your info like it sounds above), you can also send us a direct message here and we'll help you out.

It does not matter that the SERIAL NO. on the CPSC sticker is blank. The serial # is unique to each helmet and can be found on another sticker inside the helmet.

A relatively small number of helmets made it out of the warehouse without the correct internal label, so some retailers might still have helmets without the CPSC sticker. We’re reworking all helmets at our warehouse so that any future helmets shipped from our inventory will have the correct labeling. We’re contacting retailers to ship the labels for helmets they may have received but might not have sold yet.

So my helmet (L - 59/63) Arrived Fri and the CPSC sticker arrived today via FedEx.

My question is anyone having difficultly with the fit?

I have Specialized TT (M/L - 54-60cm) as well and thought the Arrowhead would fit better over the ears. Turns out ears are not much better on the Aerohead, but it's fine. What's not good is the lens digs into my cheeks to the point, I literally cannot wear.

I had a Specialized S-Works TT M/L (56-60) and it was pretty difficult to get on. I ordered a L in the Aerohead (59-63) and this one is actually a smidge too big probably. It fits fine, but is tightened as much as possible. Probably could've went a size down, but I'm very happy with it.

On a side note, I got to use it in the sprint this weekend and it's awesome! I've always struggled finding a helmet where I was happy with everything and this is the first one I've been 100% satisfied with everything.

Awesome helmet.

It was about 87 out when I did my race, but I wouldn't exactly call that heat. Anyway, I had no problem with it at all, but I've never had a problem with overheating in a helmet or at least I couldn't tell if I did.

The helmet is as quiet as expected. I would compare it the first time I drove down a freeway in a convertible. I didn't think it was gonna be crazy loud, but then you get going and are shocked at how quiet it is. I could actually hear police/volunteers at corners. Field of vision is amazing.

We're so sorry to hear that happened. We haven't heard of that with any of our athletes who have been testing the helmet, and we'd like to learn more about your experience.

With Aero helmets is it possible to group them, so if one type of helmet works well another will likely work well for that rider too?

From previous testing the Bell Javelin works best for me out of the helmets I tried including the s-works. I wondered if the aerohead fitted in to the general scheme of things or is it slightly more random than that?

You can just put the sticker right in the helmet. The serial number is printed on another sticker in the helmet, so you don't need to write it on the CPSC sticker.

Enjoy your new helmet and good luck in any upcoming races!

I also wear prescription glasses. There is definitely room behind the visor for glasses but if you are trying to place this helmet on during T1 with glasses on forget it. My procedure is to leave the visor off and next to my helmet. When I'm in T1 I quickly put on the helmet and snap the visor on afterwards. If you practice this it will become second nature.

I previously used the A2 and have thus far only played around with the Aerohead on my trainer. After an hour on my trainer my neck felt about the same as with my old helmet. My first long race with it will be in about a month. Besides with the extra speed I will gain the additional wind force will snap my head back and hold it there with out any extra muscle tension.

I'm actually having the same problem. The helmet fits perfectly but the lens left a large impression on my cheeks for hours after my first trial ride today (2 hour ride)

ok, just got my aerohead and was surprised by a few things...the size of the visor, the location of the flipped visor, and the weight.

the visor is huge, but fits well around the helmet and the magnets seem to be strong. the field of view was great.

flipping the visor, it lays about an inch above the magnet grooves. no grooves, it just lays on the top front of the helmet. every time i put it on, i kept thinking Magneto, for some reason.

lastly, this helmet feels sturdy. it feels heavier than my A2 or Attack...by a lot. will ride with it today, for a hard effort, and will be interested to see if i can tell a difference. i could see this helmet taking some getting used to for the longer distances.

FWIW, I rode the first Verona lap of IMWI last weekend with it. Helmet is definitely heavier than any other aero lid I have worn, so wanted to see how it felt on a long ride. I had planned on doing 2 laps with it, but got tired of the feeling of being "closed in" and the extra road noise, so I switched back to regular road helmet.

That siad, I had no issues with it for 45 miles and am not worried about the road noise, etc on race day. I was riding with others on the ride and the aero lid was just kind of a nuisance in that scenario. I'm still planning some longer rides with it, but will probably do so w/o the visor.

Yes it quieter than a "traditional" TT lid, but still noisier than a road helmet. When riding with others, I didn't want to deal with the extra noise. YMMV.

The difference between the Prevail and the Aerohead is +220g, or ~half a pound. If you think that is inconsequential, great. I'll still plan on doing some longer rides with it.

Never said that I don't like the visor....but I don't like the "Closed in" feeling I get with it when riding with others. I also really don''t like wearing aero lids / visros on training rides...I think it looks stoopid. But that is my own vanity speaking, I suppose.....feel free to disagree. You won't hurt my feelings in the slightest.

I wore the Aerohead for IM Canada and had no issues with it. I'm pretty sure I don't like it as much as my A2 though.

And I'm seriously questioning if it's "faster". All the photos of me wearing it, it looks like my head is tilted back slightly to see further up the road. I don't have that problem with the A2, which allows me to turtle a bit more. Put those two things together and I might have lost speed by using it.

Yeah yeah.. you never know until you test it.


FWIW... We've never been told (at least to my knowledge) who's tested this helmet. I got the feeling from talking to Jim that it was mostly the women's track team and pro team riders. All of these people are able to ride lower positions and stare at a line instead of looking up the road. That makes a massive difference.

ive worn mine in training twice just to see how it feels. I only wear an aero helmet when racing otherwise.

I don't think it is 220g heavier than my A2 :)

I was just commenting I liked the visor, until of course it fogs up at some point, then I will hate it :)

I don't wear an aero lid when riding with other either :)

I hope it doesn't slow me down too much Saturday at a little 19k tt. probably my lack of engine last couple years will do that on its own.

I tested it at UW and did not have much measureable between relaxed and looking down a bit vs. head up, looking straight out. I did find that (just like with my old javelin) the most comfortable way to wear it is to rotate it back a bit. Sitting up, it looks like I'm staring at the bottom edge. In aero, I'm looking out right through the middle of the shield. That tested well and is how I'm keeping it.

That's good to know. I'm still debating between wearing this or wearing the A2 at my next race. The visor is great but its just dark, you can't see bumps and holes in the road as well as with my Jawbreakers.

Yeah yeah.. you never know until you test it.


FWIW... We've never been told (at least to my knowledge) who's tested this helmet. I got the feeling from talking to Jim that it was mostly the women's track team and pro team riders. All of these people are able to ride lower positions and stare at a line instead of looking up the road. That makes a massive difference.

I haven't field tested yet but I feel the exact same way regarding head tilt. I'll probably rock my Scott Split at my A race the end of August.

you tilt the helmet back, adjust straps to keep it there and a good heads down position almost has the brim of the helmet level with ground. you can look out top of eyeballs and see up the road, all the while the head is low.

not saying the helmet is faster, but I will try it in a tt saturday

I think it's faster, and I've been a naysayer all along. Of course I bought it, just in case the data are true. I haven't Chung'd it vis-a-vis my A2 yet either, and won't be able to until after the season, but I think a picture says a thousand words here:



I wore it for a 5 hour ride on the Tremblant bike course, got good speed for my watts, kept my head in a disciplined position the whole ride, and had no issues with the weight or visibility (even though it was raining and fogged up, I refused to pop the visor up because I didn't want to be slow). Of course my neck was screaming towards the end of the ride, but that's with any helmet.

Finally, I find the helmet hot. So hot that I wouldn't wear it if I were racing in temps >75-80 degrees in a 70.3 or longer.

Bro.

You're not even close to riding the same position in those two shots. Your elbows are so much further forward in the first that it's allowed you to drop your head and naturally turtle even easier.

I think the helmet is pretty fast. On a 31-mile rolling, loop I usually do, I cut exactly 2 minutes (1:25:44) vs my previous PR (1:27:44) just a 2months earlier. The kicker is that this done on 6w AP less (198 vs 204). Wind was similar on both days (5 mph S). The difference might not just be the helmet as I also now had a wheelcover on my rear enve 8.9.

I agree on rotating the helmet back. First time I wore it was at a race and I could barely see anything. I was looking through the vents. After I rotated the helmet back, I had better vision.

I tested it today, during a ride that I do quite regularly. The straps were not adjusted to tilt it back, so I did have a little trouble seeing forward when I was in a low position. I was looking through the vent slits at the top of the lens. The helmet was snug and comfy, didn't really feel all that heavy, and I could feel a slight airflow coming through the vents (on top of the helmet).

The lens, while great, fogged up bad, though. I had to wipe it a few times (with my finger, which barely fit between my face and the lens) so I could see. Will baby shampoo, or anti fog solutions work? The lens does not touch my face. On the cool down portion of my ride, I put the lens on top and all of a sudden it felt like I hardly had any helmet on. Quite a different experience.

Another thing...I could tell when I broke aero b/c the air would scream around the helmet.

After I was done, I noticed that I had gone quite faster than I have for the route. I'll have to analyze later, when I get home, but I'm pretty sure I was faster at an equal or lower wattage than when I use my (training) helmet.

It was also my first ride with Giro Empire SLXs.

I'd leave it in the down position...the lens is kind of awkward if you're using one hand instead of two. I tried putting it on with the lens down and the magnets around the ears separate a little, the snap back into place.

BTW. Raced it this morning and yes it is fast although still hard to tell compared to other helmets without being in a wind tunnel, but it felt fast and the weight is no issue at all. The visor just like a few others are commenting does hit my cheek also so I'll have to tinker with helmet placement on my head to alleviate that. I now have 3 aero helmets and I guess since this is the newest I'll wear it from now on, although I might just buy different colored kits and just be one of those guys that matches head to toe.

I cant really say since conditions for the two times I was on the course I rode yesterday were not the same. wind speed, direction, temperature and actually course were all different. but the speed given watts were close. i'd have to do too much calc'ing to get a better back of napkin est that might be wrong. but I like the feel over the A2 and like the visor so I will stick with it until such time as I find it is not faster for me :)

had 29.5 mph on 311w over 33k A2, 78F, wind opposite direction and lighter vs 29.8mph on 335w over 19k and 70F. have not calc'd air densities

speeds out and back indicate it was windier yesterday on the 19k

I was wondering what people think of the gap that I have between the helmet and my back with the Aerohead? S/M Selector on the left, M Aerohead on the right (tried the S Aerohead, and it's too small).



I can only think I have a long neck compared to average, as other people I've seen wearing them don't look to have a gap like that. I tried it in a TT yesterday and from most ways of looking at the outcome, it seemed to work well, but it was a TT where I wasn't too bothered if it made me a bit slower, and I have a TT next weekend where I'm a lot more keen to save every last Watt. I wouldn't be able to differentiate between it being 2W faster or 2W slower from just one TT. So I'd be interested to hear if anyone else has a similar gap with the Aerohead but has nonetheless found it to be faster.

So, wore the helmet during an Olympic Tri yesterday. Solved the cheek cutting problem by tilting it back a bit (which actually made it have a better alignment with eyeball aero analysis) but was dealing with the lens fogging up. Anyone else have experience with this? It felt good and fast and more importantly the other athletes were asking me about it as I had the “cool gear”, but the fogging up was annoying.

I raced with it for the first time at age group nats yesterday. I had to tilt mine back a little and tighten the retention strap and it kept the visor off my cheeks.

I didnt have any issues with mine fogging up. I did have quite a bit of sweat dripping on the visor. It didn't bother me but I wasnt expecting that to happen.

Picked mine up Saturday night. Was able to fit my head into a small after removing the padding. Visor digs into cheeks slightly, but otherwise seems ok. Visor is tight against ears but not so tight as to compromise the magnets hold. Looks pretty silly standing up straight (like it's too small) but once down in aero fit is nice. Can get the front of my head much lower than in my Spec TT while still being able to see fine down the road.

Hoping to go out and do some aerolab testing in it this week.

I have a small. In picture above you can see how it fits kind of. (I have quite a bit of hair, you might get a little extra space with shorter hair) If you look at different athletes wearing it, you can kind of pick out who sized up and who sized down, mainly by how much ear you can see sticking out from the end of the visor.

It depends on how you want it to fit... I wanted to get the smallest I could get my head in... but I only TT and only have to put up with it an hour or less.

I think the biggest issue you'll find in going with the small is that the visor will dig into your cheeks most likely.

Edit: better picture for reference of helmet fit. Maybe NSFW, man boob hangin' out.

actually it's hands that are the primary thing in the way. The aerohead is actually great if your head is low'ish (at least the way mine sits) I have a much cleaner line of site than in my Spec TT or Giro Selector. You get used to it.
FWIW again, TT'ing, not Tri. Much less to dodge.

Cool. I don't keep my head that low yet. I'm working on keeping it lower. Not sure I'll get that low. Working on my strength and flexibility in upper back and shoulders. Mostly for swimming but figured it will help making a lower head position more tolerable. I'm deciding between Giro Aerohead, LG P-09, and POC Cerebel right now. I like the Cerebel but price is a little more than I want to spend. Comfort is pretty important to me. Little concerned about the Aerehead visor cutting into the cheek and the mention of visor fogging up.

true. The price is very nice and I like the visor setup on aerohead better than lg p-09. cerebrel price is just a little too much

It doesn't appear so. We have one for sessions and it's certainly not a magic helmet!

If you're taping up the vents you also need to close a bit off the underside as well to mimic the Ultimate version.

That's a really a nice feature and one of the reasons I'm leaning towards the aerohead. The lg p-09 can be found much cheaper but it doesn't seem the visor setup is nearly as good.

I've rarely had glasses fog up on me unless I've moved say from a car with a/c out into the humid warm air. I'm not really too worried about it if I buy the aerohead since it appears easy to remove the visor and attach to helmet pretty easily if it were a problem

I've used my aerohead a few times and the visor has fogged up, but it's primarily in the morning when humidity has been really high. I also used it for another ride during the day and it didn't fog up, but I noticed how much warmer it is than my other helmets.

It's a nice helmet and it def. feels faster. I also notice that if you're not in an aero position, the air "screams" around it.

The giro ultimate aerohead is going to be that much warmer then because it doesn't have the vents on top.

I tend to be susceptible to overheating so I prefer to run my P09 without visor. Not really a viable option with the Aerohead. For those who have tried both, how would you rate the ventilation for the Aerohead in comparison to the P09 with and without visor?

I don't ride the P09 w/visor, but with that being said, the Aerohead is much hotter. The P09 is a thing of beauty when it comes to heat.

I just got the helmet and have done a couple of test rides. Fogging for me (80 degrees with 90% humidity in Florida) has been a problem. I put some defog on lens and it helped. My question is how much will I give up if I use it without visor. I'm racing an international tri on Saturday in similar conditions. For reference- I have a pretty good position (for a 52 year old), running latex tubes/disk, speed concept 2nd gen. I will aim for a NP of about 220w or so (FTP 240)- course is flat and fast; I have averaged 23+ before on same course on 208w.

thanks for any assistance.

Agreed but there is nothing specific about the design that causes fogging. It may fog in rain or very high humidity which is no different than any other helmet with a visor--but the ability to easily remove it is nice !

I don't think anyone knows how much you will be giving up, but my eyeball wind tunnel says "a decent amount". The visor basically acts as the ear flaps on the Aerohead and there is some speculation that it is the visor design as much as anything else which drives the aero advantage.

There were a couple of guys in the Tour this year who ran it w/o the visor (and Tayloe Phinney did it at Nats and the Olympics) and it really doesn't look any better than an aero road helmet.

Again, this is based on my highly unscientific and I calibrated eyeball wind tunnel. I could be very wrong.....that said, I have done a couple of rides w/o the visor and it is considerably cooler w/o it.

Schitt....I have no idea. I would say "no" but that is a complete guess.

Have you tried baby shampoo on the visor? Wipe some on before the race, let it sit a few minutes and then wipe off with a soft cloth. Works great on goggles and I used it on my Selector when I had fogging issues. That is what I would do as a first course of action

I'm hoping they'll come out with a cut-out visor that effectively works as ear flaps, but doesn't shield your face. It would still have a "headband" so the magnets can mount.

I have both a P-09 and aerohead. I think there are +s and -s to each visor. I prefer the flip-up nature of the P-09, as it's much easier to splash water on your face at aid stations and I've never had a problem with it fogging. The aerohead on the other hand is nice should you want to remove the visor completely while riding, however I've had big-time fogging issues in humid weather. Just not enough airflow. FWIW I'd bet the aerohead is far less aero with visor removed than the P-09 w/ visor.

Separately, similar to others on this thread, I've found the aerohead to be MUCH warmer than the P-09.

thanks. I actually ordered the P-09 mostly because I figured for my level of performance aerohead or P-09 would both work well enough and the P-09 was over $100 cheaper on nashbar.

Somewhat of a newbie to the helmet world & Testing. No time to test unless someone can tell me where to do that in the NYC tri-state area?

here's my question -
I race with a Giro Air Attack without the lens. (have been told it tests faster that way)

i am wondering, if i tested well, how much TIME improvement would I likely see on an IM course by using either the Aerohead or the P-09? a minute? 5 minutes? more? less?

Assuming I have done all my other aero homework (Superbike, Disc wheel, 808 up front, skin suit) 150lbs, 5'8" on the edge of top 10 AG rider..

I know it's not a clear cut answer, but looking to get an "idea"

also wondering how much hotter the AH is vs the P09 per comments.. as that might really drive the decision...

From Giro via aerogeeks: "Giro tells us the Aerohead MIPS is 42.4 seconds faster over 180km (at 250 watts) than the Giro Advantage (and 25.5 seconds faster that the Air Attack Shield)."

So there you go. Probably less than a minute.

Wasn't there a whole lot of discussion about the Air Attack Shield and how that time is probably off. I can't imagine the AAS (with or without the shield) is faster than the A2.

Just trying to understand the differences? I figure when I lose a kona slot by less than whatever time difference there is, I'll consider dealing with the heat issues... at some point, if it's under a minute, it has to be more me than the equipment.. if one isn't cool & comfy, they are going to lose more time being uncomfortable than is provided in the gain. On the other hand if the time difference was multiple minutes... I'd be more considering the suffering.

I got my aerohead about 2 weeks ago and did 2 training rides with it. Serious fog issues ensued on both rides and I was concerned. I actually had to remove the visor to see adequately. I had an international tri I wanted to use the helmet but was not sure if I could race safely with visor in place. I tried cleaning and then applying anti-fog for a 3rd training ride- fog better. I then reapplied times 2 the defog and wore it for the race. In spite of high temps, high humidity, and racing with a wet head, this did the trick. NO fog and reasonably comfortable for a very hot race (Fort Desoto in St. Pete Florida). Link for antifog is below. Clean the lens well and put 3-4 drops of antifog and lightly wipe till no haze (it doesn't take much), then repeat.

Roughly 2W (doesn't say, but they probably tested at 400W so <1W at 300W). I'm guessing most of that goes away if you tape over the vents in the cheaper version. So what you really get is the carbon fiber bling factor.

That suggests that the Air Attack is faster than the Advantage which I think most would say is not based on fact.

So I was a bit worried about the fogging and cheek cutting. Used it for the first time this past weekend on a three hour ride. I live in the Houston area so average temp on my ride was 97 degrees and very humid as a rain storm was rolling in. Didn't fog one bit so not sure how others are having issues with this as I truly doubt anyone has used it in hotter or more humid conditions.

No cheek issues either. Very nice helmet.

I wear a size M or S/M in most helmets and the M Aerohead fits great on me.

I think this thing can fog--but no more or less than any aero helmet with a visor. My Javelin could/did fog. I used the Specialized TT helmet in a rainy, humid race and it fogged horribly so I ripped off visor before even leaving T1, which wasn't easy and I thought I broke it i had to pull so hard (I did not). I think aero head ventilates FAR better than those helmets based on my experience and the bonus of the Aero head is that the visor is easily removed in case it does fog

Aren't you going to fog when humidity is present and the air temp is much cooler than the temp inside there helmet?

I had almost no fogging issues with my P-09 (visor helmet), I think because it was just a much cooler helmet.

Maybe someone who did IMMT can chime in but for my friend and me it was practically impossible to see out of our aeroheads as the visor was permanently fogged.

I was going to ask about this, I have the Giro Air Attack Shield as my road helmet and its visibility gets bad on hot days. The sweat drips down the front onto the visor and on some days I have to flip it over and go without due to it getting too cloudy.

So your sweat drips and runs off of the Aero Head visor with no residue at all? If so I wonder if there's some kind of treatment or something else at play here, my Air Attack is a different story.

There is really not much you can do about sweat getting on the visor on any helmet. The only thing I do is squirt water under the visor to clear off as much sweat as possible. I get a nice refreshing blast of water on my face at the same time. You do need a bottle of water though (don't use your sport drink ;).

I thought this might be the helmet that got me to embrace visors, but I'm still not convinced. If you decide to remove the visor due to rain/sweat, does it then have the aerodynamic properties of a bus?

Recommend you try car wax for the visor, just make sure it is good quality without any grit. Liquid wax works well. Apply a thin layer to both sides and let dry completely then buff with a soft cloth. It will prevent fogging and sweat and rain will bead off it. Did this in college hockey and never had a problem in changing temps, steam and sweat.

I brought mine to the UW tunnel on saturday.
We had 13 helmets on hand, but the other two people had small/medium sized heads and brought helmets accordingly. My large melon meant I didn't get to sample as many as I'd like.

The data they provided is not so friendly as cda, so numbers will have to wait. I did find the aerohead tested better for me than my old javelin (large) and kask bambino (medium). I couldn't squeeze into the Cateye, Poc, or lazer wasp.

The aerohead did NOT test better on the other riders, but perhaps if we had a medium (or even small) on hand, that may have made a difference.

Sure, you could say that it's because the helmet was too big for those other rides, but this just illustrates another problem with absolutes. I can't fit into a medium Selector, but I can fit a medium Javelin, Cerebral, and Split. Guess which of those four is consistently slowest on me? Just because A is faster than B on subject X, does not mean it's fastest if C through Z haven't been tested. Is the Aerohead a good shout in a vacuum? Dunno, could be the next P09 or S-Works. It could also be the next Bambino...

Now tested the Aerohead. 5w slower than my goto lid. Feeling smug.

This is slightly OT but your previous post (that you've quoted there) raises something that I've thought about for a while.

My head size and shape puts me right on the boundary of a medium and large in most helmet makes and models. I'm wondering, how important is size in relation to overall drag?

I know testing is the only way that I'm going to know for sure, but if I can just squeeze into a medium Specialized Evade, is it completely pointless even considering any helmet where I'd have to size up to a large? With the old-fashioned eye-ball test, most look like melons on my head and it's sure hard to see how any reduction in Cd is going counteract the increase A.

This may also be why one size fits all helmets like the old Wingspan test poorly on many/most folks; it just may be too big for them.

I'd love to see data not only on how each helmet tested for people; but also data on their head measurement, size helmet tested, head position and angle, etc. Aerodynamics is a science, and with enough data points we could probably get a reasonable predictive model of what helmets will work well for individuals.

In my opinion and experience, yes: if you have to size up, the helmet probably isn't worth considering. I think one of the reasons why the Giro A2 tests so well consistently is that it comes in three sizes.

I'll be testing it on my TT position next year, but don't have the highest hopes for it (I've tested a silly number of helmets already).

Better angle.

Ahh :( No fun. Less track pics to google fu. I hold my head much different on the track as well.

Small aerohead was fast for me (slightly faster than my Spec TT med, sadly can't get my head in the small TT) but it will require cutting part of the visor to keep it from digging into my cheeks. Haven't decided if that makes it a no-go or not.

Off to the track this weekend to see what comes out on top there.

You seem to get your shoulders impressively narrow with the elbows so far forward. I tried that last year in the wind tunnel and it wasn't any faster. My shoulders get to a certain point and they just don't get any narrower no matter what I try.

My eyeball windtunnel is guessing a low 0.19 for CdA.

Aerohead or A2?


So far the Aerohead fogged up with a vengeance at Miami Man last weekend, total pain in the ass. Will try the car wax trick before I decide. I race in South FL and humidity is a given.

I raced Miami man with aerohead and I'm heavy sweater. Two coats with anti- fog kept the fog away. This is what I used:

A couple of drops to each side and to both surfaces on clean lens. A gentle wipe to spread and then just enough wiping to make it clear. Repeat a second time. This has worked multiple times.

So I just picked up the Large MIPS version from competitive cyclist, but am dealing with the lower part of the visor cutting in to my cheek/ cheekbone that others have written about.

I tried rotating it back, changing the height adjustment of the rear internal 'cage' but nothing has really made a difference.

Has anyone tried dremeling off a few mm of the visor? Understandably I'm reluctant to do this to a new $250 helmet. Or perhaps I can stuff some extra foam padding in the front brow area, to space the helmet farther forward by a few mm? Help...

You can contact Giro about it digging in, they now make a revision of the visor that is "supposed" to alleviate this that they'll send out to you.

In my own experience, it didn't help enough, but it might if it's close. I'd try that before taking the dremel to it. (Although, so long as you were careful, that would indeed work)

Hey, thanks for the info. I actually called Giro this morning, they asked for the manufacturing date of the helmet (9/2016) and confirmed that it indeed had the newer visor. According to them, they trimmed the visor by 4mm in Version 2.

I will probably try spacing the helmet out first and see if I can ride that way comfortably. Otherwise will probably break out the dremel. Looks like they sell replacement visors now, in case I screw up badly.

I think I can answer my own question, at least for ironmanraces, I looked it up:

(i) Helmets must be approved by a national accredited testing authority and such authority must be recognized by the International Triathlon Union and the relevant National Federation. (Please note: at all Events sanctioned by USA Triathlon (“USAT”), USAT requires all USA age-group athletes to wear a helmet approved by the USA CPSC); (DSQ)

So I guess I'll be fine with a CE sticker, since I'm not a USA age-group athlete.

Has anyone tried Rain-x for the visor to try to avoid the fog issue?
Any reason you shouldn't apply it to the visor interior?
Shouldn't it help the fog condensation bead up and roll off?

Another option from the motorsports world....antifog inserts. These are basically a stick-on double layer of plastic film (mylar or some other) that creates an insulating air-gap to the visor surface. They work very well in motorcycle and racecar helmets. Some brands are Fog-City, Invision Pro Sheild, Progrip, etc. Might be a bit of work to find one to fit the Giro visor...since they are designed around specific helmet vendors (Bell, Arai, etc), but its an option that might work.

In addition to Augusta 70.3 mentioned above, I also wore the helmet at the Cartagena 70.3. Once again, zero fogging issues and I defy anyone to find a more humid race than Cartagena.

Not sure why some of us have fogging issues while some of us do not.

It's average aero helmet as far as how "hot" it feels. I don't think it felt any different than any other aero helmet I've used.

That stated, I'm thinking about drilling a couple little holes in it for extra venting but I'm scared to do so because I know these things are designed with the vents they way they are for airflow and aerodynamics. I'll take suggestions on where to drill. :-)

I'd imagine for a helmet like this, ventilation is dramatically effected by fit, head position and speed. So different people are likely to have different experiences of fogging and over-heating.

Is there an aero benefit of closing off the tail?

Has anyone found a way of doing this? I see its a Lycra like material so allows airflow; that makes it harder to retro fit, just duct taping it over would be easy!

I have to admit that I'm in love with this helmet, I shamelessly havent tested it yet, but its such a nice thing to have on your head. Road helmet comfort, fit and presumably safety with great vision. I'd never do training rides with my selector, but this thing is a great place to be and certainly feels fast. The adjustments to raise / lower the back of the lid are also a great touch, on the lowest setting I can see pretty well up the road with a head down position.

Does anyone know that date cut off for the new spec visor, and have the contact details for the UK if mine is outside of this spec?

Theoretically, yes. Though you'd have to test to see if it actually materialized in practice. Leaving the underside of the tail open - *in theory* - would allow eddies to form back there, which would cause increased drag. In theory, the best shape for the underside of the tail is actually slightly convex - not flat - but I'm not aware of any testing of this in practice, and it would likely be HIGHLY dependent on the rider's position.

Just drill a hole through the CPSC sticker.

Seriously though, I'm waiting for someone to make a cutaway visor that mimics the ear flaps that non-visored helmets have. That way you could have an open-face version of this lid.

I tried the Aerohead today in medium and large.
Unfortunately, like other Giro helmets, they just don't seem to suit the shape of my head.
The medium is too short and just doesn't fit although the width would be perfect. The large is long enough but seems enormously wide. I'm nt sure if that matters hugely from an aerodynamic point of view. I'm sure a narrower helmet would produce less drag on it's own, but since a wider helmet will probably reduce the impact of the shoulders somewhat, it could go either way overall. However the helmet is so wide it moves around quite a bit on my head, which I don't like.
I haven't used proper aero helmets before. I bought a Casco Speedtime for this year but haven't used it yet and have had second thoughts. I'm not convinced it'll be great for drag and could be very hot. So, I was considering switching to an Aerohead and selling the Casco, but not so sure after trying it.

Helmet color doesn't really impact cooling. The foam is such a good insulator that the temperature of the exterior shell has little impact on the interior temperature.

As for deals, check eBay. I just saw a new w/o box medium arrowhead go for $151 + $12 shipping, and lots of guys selling new ones in the $225 range (shipped). For used, occasionally ones pop up on ST classifieds.

Giro doesn't allow discounting so in this instance the 15% code I have for Trisports won't work. That is why you should be seeing these for $250 everywhere as companies are not supposed to let you discount.

In this situation there are two ways to save money, one is to go the eBay route where people always end up violating their MAP pricing. In this case it looks like $229 shipped is what you got. The other is to try to grab a return from Amazon Warehouse Deals, usually about 15%-25 off if there is ANY availability.

I know you asked Jordan but I would highly recommend not doing that for two reasons:

#1) USAT takes modifying the structural integrity of the foam pretty seriously

and

#2) You have to believe Giro did their homework. Any modification is likely to hurt the aerodynamics.

If the heat is a legitimate concern you might want to look back at the P09. I myself still have my old P9, the recalled version that I wouldn't them pry from hands, which is smaller profile and should be faster. But I am getting ready to sell it as I am Aerohead from here on out.

I'm not sure how all the discounting rules work but with the VIP 20%off special going on at clevertraining, I got an AeroHead for $195 (20% off was $50, then $5 off through points or something).

Yeah I mean everyone has their gotchas to getting around their MAP pricing. Seems like nearly everyone is coming out with a program to get some sort of edge.

Some people actually want this helmet because it is smaller. But fine, I will just trade it for a new one and then sell that.

Retailers, not clubs. I assume this is why the VIP clubs get away with it

It's average aero helmet as far as how "hot" it feels. I don't think it felt any different than any other aero helmet I've used.

That stated, I'm thinking about drilling a couple little holes in it for extra venting but I'm scared to do so because I know these things are designed with the vents they way they are for airflow and aerodynamics. I'll take suggestions on where to drill. :-)

Knowing that you are from the Houston area as well; how have you been dealing with eye shield fogging? I have found it basically unusable, even up at IM Maryland, having to remove it to be able to see.

Heat is the concern I have. I just got the aerohead and only wore it once for a quick 40 minute day before race warmup ride. It did fog so I'll have to try some of the anti fog solutions. I'll be trying it on some warmer rides because on the short ride it did feel warmer compared to the lg p-09. For me, the aerohead is far more comfortable as the lg p-09 is sort of clamped on my ears as opposed to aerohead which nothing presses on my ears.

One thing that hasn't been mentioned for helping with fogging is using toothpaste. With any visor or shield, there is a thin film layer when its brand new. Put some toothpaste on the inside and rub it in real good. Let it sit for 45-60 min and then rinse it out. I've used this method for diving/snorkeling/scuba. Works pretty well and is free.

I had some fogging with my Catlike visor last year and tried the fogging wipes I got for free and tried baby shampoo for my race last weekend but then it got cancelled. I will have to test out toothpaste before my next race. Not much worse than not being able to see out of a visor during a race. Well there are a lot worse things but it does suck.

i tested this with an athlete... it was on par with an aero road (Evade) helmet with the visor flipped up, but large gap between it up and it on as designed. Also, removing it completely instead of flipping it up was ever so slightly better.
On one athlete, so obviously disclaimer ymmv. but yes, significantly less aero.

I did my first 70.3 in the Aerohead. I liked the helmet but after two hours, I was annoyed with the visor resting on my cheeks as others have mentioned. No prob for a half, but for a full this is gonna be rough.

I called Giro today and asked about the new spec visor to see if I had the old one or the new one and the rep had NO idea what I was talking about. Put me on hold to find out and did not find anything about a new visor. She simply came back and said that she wasn't sure about a new visor but they would just ship me one ASAP. I would like to note I am very impressed by their service department being so eager replace. I was not being rude nor did I express discontent, they just wanted to make me happy. For that reason, Giro has made me a big fan of their company as I place a premium on this kind of service.

In any event, how do I know if I have the old visor or the new one? My helmet has a MFG date of 07/16. Cant seem to find the visor date cut off anywhere. Worst case scenario I have a replacement I can try to file down to a more comfortable fit.

Tested it twice now. Once on my pursuit bike in my UCI legal position and the other on my TT bike in my CTT position. The result were it was slow on the first and really slow on the second.

Also worth noting that an the AeroCoach Facebook page you can see that when they tested it on Hamish Bond it was the worst performer (the S-Works, Cerebral, and Wasp were all faster). That said, it is very fast on some people. Just goes to show how the marketing is BS when it's so reliant on individual position.

anybody find this helmet a bit warm compared to lg p-09? I have both and need to get out on some warm days and test with the lg p-09 to see if it feels warm to make sure it's not just my imagination making me think the aerohead is much warmer. It's possible the issue is with lg p-09 in the past I've worn it with out the visor so more wind to cool me off. I had a sprint race this past weekend and with the aerohead sweat was just pouring down my face. granted it was a little warm and I need a haircut. I do prefer the aerohead for comfort but I'm concerned about the heat.

Yup...tons of sweat for me too. Without the visor it is just fine. I wonder if it has anything to do with exhalation being more likely to get "inside" the helmet with the visor on.

without visor is fine but I thought I read it's much slower without visor. I thought I read somewhere that the lg p-09 tested faster or at least as fast without visor. so lg-p09 without visor is so much cooler.

Raced my aerohead for the first time this weekend. Went from a Lazer wasp air. Agree that it's warmer, but not so much that I won't wear it for IMFL later this year. Really comfortable, and race was 80+ degrees with nearly 100% humidity and had no fog issues. Sprayed the visor with rainx. Only issue is jackass knocking it off the bike in transition and having to find the visor and helmet on the ground after the race.

Thanks! Good to know. I haven't tried mine outdoors yet and planning to use it at IM Copenhagen in late August. Weather is usually "cool" in high 70's/low 80's. But it could rain and I don't believe it will be humid.

I actually have the non-triathlon version, Aerohead Ultimate, got it on a highly discounted deal from a friend. Not sure if I'll be frying afterwards. Anyone have any experience with this version?

Thanks!

I find it really comfortable. I'm not anywhere close enough to FOP that, if it is faster for me compared to lg p-09, that it would make any huge impact. but I like the comfort of it. The visor I find really nice. the lg p-09 is fine I just don't link how it closes down around my ears. I had fog issues on first ride but used some product recommended here and it's been fine since.

I have the Ultimate. Haven't raced much in it (wore it 3 times). It's just as hot as the aero helmets I have used. But, I don't notice these difference very well, all helmets (incl Road) are hot to me ;)

Visor has fogged up once (hot and damp) , but I hadn't used my usual dish soap for it. The other times I did I had no problems. The selector and Scott Split I had also fogged up when I didn't use this. After this weekend I will know more, have 2 races (60 and 70km tt's, so enough time to get hor or not! ) coming up this weekend.
I do TT's instead of triathlons though.

Hey, thanks for the info. I actually called Giro this morning, they asked for the manufacturing date of the helmet (9/2016) and confirmed that it indeed had the newer visor. According to them, they trimmed the visor by 4mm in Version 2.

I will probably try spacing the helmet out first and see if I can ride that way comfortably. Otherwise will probably break out the dremel. Looks like they sell replacement visors now, in case I screw up badly.


I called Giro right now and they told me that they never updated the shield/visor for the aerohead, just the attack. Seems like we are getting different answers.

I feel very comfortable with the helmet, very spacy and it is better to me than my old Giro Advantage with sunglasses. As a matter of fact, I had a headache during my last IM I think because of the arms of the sunglasses between the helmet and head. So at least that problem is solved.

The only problem I had upto now with the Aerohead was the lost contact lens. But that's not a killer for me, I still have the other eye and even if they fall both out I can still race, having only +2 on both eyes.

Lost my left contact lens yesterday again, closed the left hole in the visor now with tape, see if that helps.
Grinded 5 mm of the bottom of the visor, because it was resting on my cheekbones.
Always something to tinker...

Small update:
Rode the Aerohead (standard version) in Kona and it was great, did not notice the helmet: no problems with heat or fogging. No issues with my contactlenses either.

I do not have experience with the new Air Attack and Bontrager's aero road. Also, it seems that different people have different experiences with the Aerohead. So I guess you have to try it out yourself.

I‘m afraid you can‘t see a lot (but it should look like that of course) but I removed at least 5 mm from the bottom edge. As I already said, with a table grinder such that I could hold the visor in both hands.

There was a testing session with 2 pro tour riders a couple of weeks ago. Both were faster with the sworks than the Giro. One marginally, one more significantly

Anyone have experience with using a thinner padding in the Aerohead? The medium fits great without padding for me, but a bit tight with it in. I have a Giro A2 and a Giro road helmet both in medium.

Called Giro to ask about a thinner padding and they are checking for me, but wondering if anyone else had similar experiences and found a good solution.

Just take he padding out. That said, the padding will flatten out with use, maybe take it out and put it under a book with a weight on top.

using a thinner padding in the Aerohead? The medium fits great without padding for me, but a bit tight with it in. I have a Giro A2 and a Giro road helmet both in medium.

Called Giro to ask about a thinner padding and they are checking for me, but wondering if anyone else had similar experiences and found a good solution.

Small update:
Rode the Aerohead (standard version) in Kona and it was great, did not notice the helmet: no problems with heat or fogging. No issues with my contactlenses either.

Do you have a photo of the visor ground down? Thanks



I‘m afraid you can‘t see a lot (but it should look like that of course) but I removed at least 5 mm from the bottom edge. As I already said, with a table grinder such that I could hold the visor in both hands.

I had to buy a new visor because the old one broke (not because I worked on it, but during transport).

The first thing I expected to do was grinding off the bottom edge again. But firstly I tried it on and the strange thing was that it did not touch my cheek.

Comparing the old visor with the new one reveiled: Giro has done its homework. They removed nearly a centimeter from the bottom. So no grinding no more.
