I have the Enve SES aerobar system, but not the stem. I had to use another one, but I have to say all of the fitters that have seen this system were blown away. The flexibility is incredible and now that it's on the bike, I absolutely love it. The independent tilt of extensions, the ability to choose the extension type you use, mounting options for those pads and extensions are some very nice features. The basebar ends are textured so you don't need bar tape. It's a very well thought out, really nice system.

There seem to be a lot of assumption that the Aeria Ultimate is fast in the tunnel, but have we actually seen anything that indicates this yet? It looks good, but I haven't seen any data, or hint of any.

2 things about this:

1. the designer of that bar is on the forum, so he'll tell you i presume. he's got software which can aero model, which he designed himself, so he is not naive to aerodynamics as a data point in product design.

2. of all the things on the bike that i'm not particularly aero-obsessed, the bar is at the top of the list. i'm much more interested in adjustability, ergonomics, and sturdiness. after that comes cable routing, integration with stems. somewhere way after that comes the aerodynamic performance of the bar itself (sans rider).

Too much frontal area associated with all that Enve tilt hardware, especially if extensions are under the bar. Plus the cable routing on the Enve bar makes the build an absolute nightmare and then the turns in that routing are so tight / sharp that if you're using rim brakes or mech actuated hydros the modulation of your braking is compromised. You also have to consider your preferred bull horn position. The grips are really swept forward compared to other bars and if you have an aggressive position and/or a lot of pad stack and/or short arms you might not like this. I actually do like it because with the under mount setup and normal arms the bullhorn location relative to my pads isn't that crazy. But I know people who hate this aspect of the bar.

I don't have any experience with the Aeria thing but I know it's what I would buy if I could hit my stack on it. I'd need a 54 P4, which I have actually considered buying so I can try this bar. I just can't wrap my head around buying a bike with notoriously poor braking and clearance issues.

Anyways I think the 51 Speed Shop front end at least belongs in the conversation here, as well as the Alpha X, which is surely the most aero. The Culprit bar/stem should probably be considered too -- we don't know enough about it yet though.

The Enve bar and the Zipp bar are both long in the tooth. They are old bars and front end systems and neither of those companies seem to give a shit about updating them or innovating in this space because they would rather focus on products normal people actually buy on which they actually make money (i.e. wheels). I don't know why anyone buys one of those bars with all these better new options hitting the market

I haven't seen any aero data and while I haven't asked him but he has heavily hinted here that the system with the new bottle is quite a bit faster than without. I just don't like integrated hydration like that on my bike, but if it is fast enough and functional enough that I guess I'd have to consider using it on race day.

I would wait to make any decision until the week of Kona. Just sayin'. ;-)

Jim Manton / ERO Sports

what kind of hydration do you like? and look, i'm in the minority. whenever i ask pros - good pros, smart pros - whether they want to slap a bottle gotten on the course into a between-the-extensions cage, and then reach down, grab, pull it out, drink, replace it, that's what they choose. me, i think grabbing a bottle, squirting its contents into a refillable integrated bottle with a drink straw, i think that's far, far better. but i appear to be the only one who thinks so.

I like a round bottle between my arms with the cage securely affixed to the stem, preferably via bosses on that stem, and a round bottle behind my ass with the cage zip tied under the rails.

There are round bottles on course. I can ditch the round bottles I start the bike with. Round bottles are easier to clean, easier to replace, etc. Really loved it when I bought a brand new X-Lab BTA bottle and launched it right out of T2 on a brutal speed bump -- there went $40.

I don't have to deal with sticky shit all over my front end because I get my calories from fluids and in my experience all of these BTA non solutions inevitably leak or spew and probably corrode your IA extension clamps, so these BTA solutions on a Felt may even lead to death or, at minimum, dismemberment.

The straw part of the system is intolerable to me. It has to be cut to the right length for where my head will probably be when I want to take that drink, which varies. When I'm racing my head position is moving up and down depending on what I need to see in front of me. When I know there's nothing ahead that's going to launch me off my bike, my head is basically in my hands. Which means I need to fold this straw down every time I'm not drinking, and pull it back out when I want to drink. That's a very similar level of effort compared to just pulling a round bottle out and drinking from it, which is in and of itself a lot easier when you simply do it while you're climbing/going slow. When climbing you will be out of the saddle anyways. The aero penalty for that drinking will be immaterial and almost all courses have enough out of the saddle hills where you can drink only during those opportunities.

There are other things. Like how it's really difficult to get some of these systems in the right place in my cockpit fore and aft, because of my undermounted extensions. I could go on.

Don't get me wrong, I buy into the theory that these BTA solutions are better, but in practice they have never worked for me. Maybe the system on the Canyon (or the Scott) is the winning ticket -- those I haven't tried. But honestly my experiences with PD BTA products haven't been great

well, like i said, i'm in the minority. how i deal with sticky shit on bottles: i clean them. how i deal with the straw: i cut it to the proper length. but then i'm a recognized leader in my field, and i can't assume others can clean a bottle and cut a straw to length with the same skill and talent that i possess.

Yeah it's not optimal for under-bar mounting, but otherwise it's a non-issue since the tilt is built into the riser system.

I have the Enve bar on my track bike, so I can't comment about cable routing; but I like the lower, more forward hand position on the bullhorns and overall adjustability is good. Another thing about the Enve bar is just how well it's made; much sturdier than my Tririg Alpha, which feels downright flimsy in comparison. No way I would ever think of using the TriRig for standing starts on the track, but I have no such hesitation about the Enve.

Yeah, I have to agree with this assessment. The Enve bar is shockingly rock solid, especially given that it's a two piece system with a standard stem clamp/interface. Going from the Alpha Classic to the Enve bar was like night and day, and Alpha X falls somewhere in between. The HED Corsair was up there too in terms of rock solidness. Of everything I have tried, though, nothing beats the Trek Speed Concept, which is maybe the most aero and most solid front end in existence outside of the Premier Bike Ventus III, but I think that Tactical front end has limitations in adjustability relative to these other market-leading front ends we are talking about.

"of all the things on the bike that i'm not particularly aero-obsessed, the bar is at the top of the list. i'm much more interested in adjustability, ergonomics, and sturdiness. after that comes cable routing, integration with stems. somewhere way after that comes the aerodynamic performance of the bar itself (sans rider).

With these priorities, what bar on the market today is your bar of choice?

Scott

I think it's the mess that can happen during a race or training that is most annoying at least to me. Theoretically, I prefer the method described by you (and used to do that) but gave up on it as there were too many real world issues as outlined by Kiley, among others. Now, its water BTA (as even a regular BTA bottle can leak) and calories behind the ass or perhaps also in downtube for longer course

Right now, bang for buck, its profile t3 w/j5 bracket and any old base bar.

Dan Empfield

The graph below requires a little bit of explanation - in order to fit data for rider on and no rider I've normalised the Aduro curves to 100%, so the Aeria Ultimate (AU) performance is shown relative to that.
As expected - the Aduro is amazing with no rider thanks to the minimal frontal profile. But the AU went ahead with a rider on. We took the AU off and repeated the Aduro test to verify the numbers as the magnitude of the relative performance change was so significant.


The AU offers better pad-basebar separation thanks to the dropped wing. And the wide pedestal base (and wider extension clamps) means there is better airflow over the centre of the bar.
The Enve tested out basically the same as AU with rider on (slightly slower at low yaw and slightly better at high yaw).

One bike brand has tested the HSF Aeria bottle and had a massive performance advantage. If that increment is consistent across frames the bottle will be a must have. I'm trying to get testing sorted to evaluate a variety of frames. The impact on frames with narrow headtubes will have to be assessed before any claims can be made for universal benefit.

There is also a satellite magnet mount for the hose, that allows you to orient the straw close to the hands so you're not reaching back to grab it. With the aim of minimising the movement required to hydrate.

One thing to note with the Aeria 2 is that it's a platform that will continue to be built on. Firstly there are other armrests on the way (that will fit all PD bars) to offer different fit options. Of course, I didn't take any photos of them at Eurobike so have to rely on others - this is the race armrest - intended to tightly cup the arms for narrow positions. I was going to arrange for a sample to be sent to Slowman but a World tour team got in first so there are no more samples left. There is another armrest that offers a more gentle curve for general use.

There are other Aeria 2 items on the way, some just alternatives, others will be unique innovations.

For me bars are all about fit - which is why the AU has the largest fit range of anything that doesn't have sliders (which just offer smaller x increments for Felt and Trek). The Enve has limited width adjustment and large steps in X. What I don't like about the Enve is the weak armrests that don't offer a firm control base.

By having a range of extension options, 15deg of built in tilt, 7.5mm x increments, 5mm stack increments and 18.5mm width increments as well as (soon) 3 armrest options you will need to be a very special snowflake to not be able to optimise your position with the AU.

One of the criticisms of the AU is the weight of the stem, but now the Enve is 100g heavier so it's pretty clear that these type of stems are not light!

Bang for the buck aside, do you see any downside associated with the Aeria Ultimate relative to the T3/J5?

Scott

Can the AU be configured for a standard bottle BTA?

"I like a round bottle between my arms with the cage securely affixed to the stem, preferably via bosses on that stem"

Scott

Yes, the bridge for the spacer pedestal can have a BTA attachment added.
You have fore/aft adjustment by choosing which of the squares locks into the hole on the bridge:


This is the same BTA mount that fits on the J5 bridge.
I realise that the instructions for the AU are sparse and that this sort of info should be covered, I shall be taking charge of improving the information for the bar.

The downside of any integrated bar is less flexibility compared to a modular setup. However, the AU narrows the differential to the point that there isn't a practical downside. The modular bars can get the pads slightly wider but we're talking 27 vs 29 cm so it's special case territory anyway. Obviously the cost is a non-trivial factor, but that mostly goes towards speed.

Thanks for the detailed response! Your transparency and the substance of your replies says a lot about the thought behind the bar.

Here are a couple more for you, if you don't mind:

-Any concerns about running Magura RT8 brakes on the AU?

-The reach from the BB to the back of my pads is 485, of which 437 comes from my size 58 P3 frame. How would you recommend replicating those numbers with the AU? In other words, can I get there with the 70mm or 100mm AU stem?

Thanks again,

Scott

Any tilt options for A2?

no downside. great bar.

I may be right behind you. I'm having trouble finding a reason not to buy this bar.

Thanks for starting the thread!

Scott

How did you select your stem length? What are your plans for BTA and computer mounts?

Scott

Nothing I can think of.


And now we come to (part of) why PD engage my services as a consultant - I've modelled the fit options of most aerobars on the market for the velogicfit bike finder so can calculate the fit for most bikes/bars.
Your Pad Y still 660?


Accuracy is radial distance from target in XYZ.
You might choose to slam the steerer spacers in favour of more under the pads. So 10mm on the steerer and 30mm under the pads will move x forward 3mm and should give you enough clearance to use the Bridge and BTA.

The integrated bottle is still a few months away from hitting the market. It's not an easy thing to make.

Wow, thank you! Very helpful, great advice.

Love the idea of 10mm on the steerer and 30mm under the pads.

My Y is currently 665, so very close!

Is the Z (100) in your model referencing the 100mm AU stem?

Scott

Ext Z is the separation of the extensions (c to c in mm) - which is fixed on this bar but becomes an important variable on clipons (hence inclusion in the models)
Pad Z is the armrest width (c-c)

For 665 you could just add in the bridge (5mm) on 30mm spacers

Ahhh, I see. Fwiw, my pad Z is 245. Based on what I've seen elsewhere, I should be able to get there on the AU?

Sorry if I missed this, but which stem did you model / recommend?

Scott

closest pad centre is 252mm, note that the F40 will effectively be wider than most so you might want to go in a step from there
For the stem - I've highlighted the relevant cell

Not sure how different the bar is but it looks like the New Cube runs Profile bars with Magura brakes.

I wondered if the drink system on the Cube is also Profile Design as it looks quite similar to the new system.

Got it, thanks again! You are tremendously helpful.

Cheers,

Scott

The cube uses the brackets from the Aeria Ultimate but their own basebar.
I haven't seen any images of a drink system for it, I don't know what they're using.

Trisports only had the 70mm stem left so that was chosen for me. :-)

That stated, I would have selected the 70mm anyway since I only need about 75mm of effective stem length to get my pad reach of about 500mm.

I haven't thought of BTA or computer mounts yet. I'll probably just keep my Xlab torpedo cage and see what real estate I have left for the computer.

He just said there's potentially a massive performance advantage associated with the integrated bottle. You're not going to try it and see if it works? I guess I'd probably give it a shot if I had this bar

Sorry, meant the width between armrests. It doesn't matter for the XY calc (as all the adjustments are independent).
You would need a Cobb or STS headset cover. The minimum I've used in the system is 9mm (as that is common) so a Cobb would get you right on the Y target and 1mm from X.

Not yet available. I'd also like to add that I'm not sure it would play well with the Dimond brake cover. I haven't found one single BTA system that "hangs" between the bars to work with the Dimond.

Would I be better served with the 100mm stem?

You can use the long stem, but your accuracy slips out by 0.1mm!!
To clear the dimond brake cover you're probably better with the long stem and it would give you a chance at the bottle.
You can see the Stevens has a bayonet here and here - the Bottle is a fair way ahead of the HT and the rubber gusset gets cut to match

Thanks! I ordered the 100mm stem. Despite it causing my fit accuracy to be off by .1mm.

I am using the Garmin mount with the o ring type straps on a cheap clamp on computer mount and it works awesome. I wasn't aware that the extensions were a different diameter? This is the one I have....https://www.amazon.com/...ter%2Bmount&th=1

Which one are you talking about? Enve bar uses standard width extensions, I know because I've replaced them with Profile Designs...

The extensions start out at the 22.2 standard size, then as they extend out they get thicker. Thats why none of the standard garmin mounts work.

I never noticed, must not be much of a difference. I didn't use those extensions for long, but I did have a garmin mount attached. This is the mount I have, it's a two-piece bracket so it fits even if extension size is a little off standard.

Installed the PD Aeria Ultimate bar and stem today. I couldn't use the stem cap or stem expander as they didn't fit in my 1 1/8" steerer tube. No real biggie.

The bridge you are showing in your message is not the same as the one sold separately that can be attached to the J5 brackets itself.
http://www.trisports.com/...n-j5-bta-bridge.html

It looks like the one you have has to be used like a spacer below the armrest?! (you cannot bolt it to the J5 as it is "integrated")

Did it come stock with the aerobar?
Doesn't PD provide a picture or explanations with the bridge?
Do you think it could it be used with other PD extensions?

Edit: link not working

No, the instructions don't show how to do it, as mentioned - they are woeful.

The J5 bridge only fits the J5 clipon bracket
the aeria Ultimate bridge that the GMAN is referring to only fits on the AU. It replaces a 5mm pedestal spacer.

Yes, I guessed!
Will a BTA bridge that can work with other PD extension brackets be developed one day?
Seems easy to do, and there is nearly nothing on the market...
thanks

I figured it out. There are no instructions at all when it comes to the BTA mount. None. There's not even a mention as to what it is. Had I not seen it in this thread already I'd have no earthly idea what it was.

Additionally, the half a page instructions for the whole setup (yes, that's all you get is half a page) include this line about the armrest spacers: 4. Aerobar bracket riser kits are included to increase the armrest height. Choose the amount of height increase needed and corresponding bolts using the attached chart.

There's no attached chart. There's like 10 different hardware bolt sets that are clearly marked but there's no chart. It would have been nice for some mention of what the base stack is with the tilt hardware. I had to figure that out. It's 20mm for those wanting to know. So I put on another 20mm spacer plus the 5mm for the BTA bridge with a slam stem. So I needed the 45 mm hardware bolt set. Once again, it would've been nice to have that info in front of me so I don't have to figure it out on my own.

A to A+ grade for quality of product. Super nice bar and stem system.
F for instructions. We are talking about cheap, Japanese toy level of instruction manuals for an aerobar system that costs $1,200.

Others should follow TriRig's lead on this. Their instructions on their website for the Alpha X are near perfect.

I do agree the instructions are very poor. Plus there is very few picture of the whole setup assembled, so for the routing part through the stem it's basically a trial and error..

@[The GMAN] Can you send a picture of your setup and some explanations regarding the BTA? I have the parts, but didn't spend the time to try to figure it out yet..

I had to nix the BTA mount for now. The tilt extension spacer thing has to go on top as it's affixed to the armrests, and the BTA bridge spacer goes between the aforementioned tilt thing and any other armrest spacers. In order to use the BTA bridge and mount you need about 30-35 mm of clearance underneath for the Aeria Ultimate stem top plate. I only have a 20mm spacer underneath right now. We shall see after I ride it a few times whether or not I need to add spacers.

I will take some pics later of what the BTA bridge and spacer looks like together.

Does anybody have any pictures of the stem and bar set up together yet? Pics online still seem scarce. Trying to set up on a new P2 with Tririg brakes and Di2. My mechanic has some reservations about some of the angles the rear brake cable will have to make if routed internally through the bar and stem and through the top of the top tube.

Sweet jesus, those clamps from the Eurobike pics are lovely.

My favorite extension to this day is the Sonic Stryke, with the original exit holes removed, and new ones drilled through the back of the extension like these ones. The ergonomics of that bar are easily as good as Zipp's EVO 70.

Currently I have them strapped to a custom USE Tula inspired base bar I built, as they are the only extensions around with a flat mounting surface on the bottom. I'd wager they could be retrofitted to quite a number of different base systems that now exist.

I had no issue routing the brake housing and cable through the bar and stem. TriRig Omega X brakes and Dimond frame.

I'm hoping to use the stem with a tririg front brake (with the 'no hanger back plate') and a PD Svet basebar. I have the stem but it doesn't come with a cable stop for centre pull brakes. CycleNutz is trying to get PD to send me one though, so fingers crossed. Will post pics if/when I get it all sorted.

PD Customer Service sent me the cable stop about a week ago. Haven't had a chance to mess with it yet. I'm trying to do roughly the same thing with a different basebar than your Svet.

CS was pretty insistent that the stop won't work unless you have a base bar with the cables coming out the center of the clamp. I've got a base bar I've modified to route that way which I'm going to try it with. I can also try routing another way. Not sure when I will get to it though. I will post pics as well whenever it happens.

Thanks. The aim was a clean, low stack setup with lots of adjustment. It has turned out pretty well.


Pity they were so short (and I am not). I might suggest that you watch this space though...

While I appreciate the sentiment - you are clearly an engineer with connections that gets shit done, I'm an engineer that just builds it myself.

I have a Lulzbot Taz 6 with nearly a 12x12x12 capacity, so anything I can imagine is generally something I can bring to life these days.

The Stryke's length was perfect for me. I have a short upper body, but long arms (moreso in the upper rather than the forearm), so they are just fine.

Could someone who owns this bar clarify the min/max pad reach offset values from the center of the bar. PD claims "Reach: -21mm to 92mm". Their graphs suggest these values are to the rear of the pads. However, these seem way off. Their claimed stack values of 25mm - 105mm are a joke, so I'm assuming these reach values are measured to some other (mysterious) point as well.

After some thought, could the reach values be -21 to -92? These make more sense.

If you can, shed some light, please.

Hi Jim - was there a new bar announced in Kona?

I have have a couple pics to share. Please have mercy on my spacer-abusing soul.

Huge thanks to Cyclenutnz.

I am really happy with it thus far. It came out pretty clean from the front. The only real issue I’m having is finding a home for the junction box. The 5 port doesn’t fit in the 70mm unless I am doing t wrong. I may just have to stick it down where it is. I originally had all the wires exiting the rear, but seems even with a new PD ATTK IC, there isn’t quite enough cable from the horn shifters to get that far. Any suggestions would be welcome.

The cable stop works, but sort of an interesting design in that it angles back toward the head tube and not really toward the brake on the 70mm.

I don't know where those stack numbers came from, but I can clarify for you
The minimum stack of the bar on its own is 47.5mm including cushion
The stack of the stem is 12mm (+- a tiny bit if your HTA not 72.5deg)
So the minimum total stack is 59.5mm from the base of the stem. Add the headset cover to get stack from the top of the frame.

Actually, looking at it I think someone has calculated the comparative stack. So the min bar stack would be ~25mm if using a -6deg stem.

The reach values have been given relative to the frame xy point. So 21mm behind the frame reach through to 92 in front. That should really be explained on the page.
If you want the values for bar only the max setback is 91mm (to rear of pad).

Hope that helps

I'd put a JC41 inside the stem and route the basebar shifters to there. Then you only need a 3port

Have noted feedback about cable stop angle, happily I wasn't responsible for the execution of that concept.

I am finally getting down to giving this a try today. Do you mean a jc41 for each set of shifters, or that with a jc41, the 3 port will also fit in the stem?

I may just be approaching it wrong. The issue I am running into, is that any of the 4 wires if internally routed direct to the 3/5 port, will not have enough length to allow the 3/5 port to reach the bento. The bar ends reach about to the cavity in the stem, and the base bars reach out an inch or two but not quite far enough.

Hmmmm. Looks like the cable stop is foul on the head tube if you try running the stem slammed.

Did PD actually try fitting this to a bike before releasing to the market?

This awkward angle is present on the 100 mm stem as well. But it's not a show-stopper.

Also, the stem doesn't seem to play well with low profile headset dust caps. The one on the picture below has 4 mm of stack, and the bulge on the bottom of the stem doesn't allow the stem to settle on the dust cap on all sides (it rests on the bulge). I never would have thought I'm going to hunt for a dust cap with more stack:)

Is that an Orbea? How do you like it? Any qualms about having to shim the steerer tube?

Yes, that's an Orbea Ordu. I have no complaints. Obviously I was not happy with the Vision cockpit that came with the bike, thus my hunt for a bit lower and more adjustable one. No trouble from the shim on the steerer.

Can you post a picture that shows how the stem and bar looks on that frame?

Here you go.

I added 7 mm of spacers underneath the stem. It would probably be nice to print/mould something to take up the empty space between the spacers and the frame. Other than that, I think it looks OK.

Thanks. I've been thinking about a ride exactly like that one, you even got the colors right ;-)

Does anyone now the width of the stem clamping area for the aeria ultimate bar?

It's a typical 31.8 mm.

Yes, but how wide is the central section were the stem clamps? I.e. how narrow does the stem need to be to fit?

Jim, was this new bar announced yet?

Hello,

Can you post a pic of the AU on your P3?

Scott

“The cable stop works, but sort of an interesting design in that it angles back toward the head tube and not really toward the brake on the 70mm. ”

edit; nevermind, wasn’t sure what a cable stop is, figured it out and see your point.

Scott

Hi Jim,

Other than the obvious benefit of stack flexibility, what advantages does TriRig’s Alpha One have over Profile Design’s AU (or, vice-versa)?

Alternatively, do you prefer the Alpha X or the Aeria Ultimate?

Just curious as you may be one of the few to see each bar in the wild. Plus, you brought the Alpha One into the discussion. 🙂

Scott

Still happy now that you (presumably) have some time on the bar?

Ps - You should update the OP to include a pic of the Aeria Ultimate (vs Enve).

Scott

The One is $200 cheaper, so that's good. As you stated, greater flexibility of stack with the One, but more fore/aft adjustment for the Aeria. The One is certainly easier to adjust, but I understand the concerns over reliability, and that has to be answered. Pick 'em, but in the looks department, the One is certainly sexier. For Gucci Factor, it wins hands down. I mean, let's just be honest here, if you believe it's reliable, you're going to pic the TriRig for that reason alone.

The integrated hydration on the Aeria is possibly an aero improvement, though fugly as hell. That, though, is likely frame and athlete dependent.

i had to use 3T aerobars because cabling was impossible for eTap with the original aerobars
Aeria Ultimate base bar + 3T aerobars

see pic here

Does anyone know if Profile will be offering this Aeria stem in 120mm?

Definitely not. By the end of 2018 all the PD aerobars will have a similarly expansive x fit range to the aeria ultimate. Longer stems become such an edge case that they can't be justified.

There will be a flatter angle stem.

Pity. I suppose I will have to create some kind of hack to attach the little mounting bracket for the Aeria hydration system to a non-Aeria stem - I really want to use that system.

I don't like your chances, the stem and bottle shaping is quite specific.
And you don't want to be drilling stems.

Is your aim to use the stem/hydration with current bar?

You’re underestimating my Dremel skills! I could see reshaping and securing the mount to a different stem using a two-part epoxy, but I agree ... there’s no way I would drill into a stem.

The bar is a use Tula, which is the hitch ... if I didn’t like that bar so much, I would be tempted to get the full Aeria system. But that would mean I would be spending 1G just for no reason other than running the hydration system, which is not the most sensible approach.

The potential aero advantage of the bottle might make the 1G worth it. Depends on your frame. Don't have shareable data yet. Which bike are you on.

Qr cd0.1. That’s the rub ... a long and low frame, with a long stem.

But tour earlier teasers of some of the data, and Jim’s earlier findings with the torhans-close-to-head tube config, have definitely got my attention.

100 to 110mm "X" lenght, more "Y", Integrated junction box (even if it's just the new one EW-RS910 I'm willing to invest) with access to press button and charging port, a bit lighter. Where do I sign ? ;-)

In the event everybody hasn’t turned their interest to the new Tririg bar, I switched to the 100mm from the 70mm and it seems to work a lot better. It took a little finagling but 5 port fits inside and there is a hole on the side that isn’t present on the 70 to access the charger port. I’m not using the included cap at this point because i am experimenting with position at the moment and don’t want to commit to cutting the steerer yet.

Hello,

I see the HSF Aeria Bottle is now on the market. What can you tell us about the benefits of using this bottle with the AU Bar?

Scott

Not a lot, I still don't have one so it's quite hard to test.
One bike brand has tested a significant boost to bike performance from using the HSF Aeria, but that data isn't shareable.
The aim of the bottle is to make 'mortal' bikes super, so the gusset is intended to be cut to tuck up against the head tube.
Comes with a satellite magnet so the hose can be positioned up by your hands.

A definite benefit is that it's very good value - for the cost of development it should be about 3x the price...

I assume the part on the lower back is a bento of some sort. Is that correct?

Is it required to mount the system? There's no way that part is going to clear the head tube/front brake cover on my Dimond. I don't think it will clear the cover without that bento part either but I'll try it out to see.

Favorite Gear: Dimond | Cadex | Desoto Sport | Hoka One One

That's the gusset that you cut to match your frame.
As shown here:


It is optional - clips on to the back of the bottle. But it's part of the package - giving a smooth transition from bottle to frame.
Doesn't store anything unless you are both creative and extremely dextrous (would not be easy to access).

Thanks. That gussett definitely isn't going to fit on my bike but I'm going to see if the bottle will work.

It mounts directly to the stem. The stem, not the bar, is the one and only component necessary for the HFS Aeria.

---

Favorite Gear: Dimond | Cadex | Desoto Sport | Hoka One One

How much does it protrude below the stem? What are the overall dimensions?

The HSF Aeria doesn't fit on the PR6 stem at this point. It can only go on the AU stem.

Any thoughts on the impact for an older P2?

This is a lot like a box design I was playing with using a 3d printer. I'm very interested but want more information first.

Can the HSF awria fit on other bars provided one uses the Aeria stem?

Thanks

I would be interested to see if you can manage to actually fit the charger to the junction box in the stem.
I did the same with mine but made sure i fully charged the battery before fitting - not the best long term solution mind you!

That's why I ended up keeping it outside of mine for winter training until I find a better solution (probably with the integrated bottle...), or will only insert it in the stem by race season time.
For now I used the round holes on the right side and have the junction box in front of it, managed to make my junction box works with only 3 wires by having a 4 ports JC41 inside the stem. I know I can do two wires with the new EW-JC130 wires but not in a rush to change.
Really looking forward to that bottle availability, it's probably the missing part of my setup right now !

cyclenutnz: By flatter, do you mean more drop? or less drop?

Less drop. I'd describe the current stem as declined

Yes, as long as the extensions are not too low (~50mm stack) or too narrow (less than 100mm)

Makes sense and thanks!

Would it be possible to use the HCA as a storage device and run a BTA over it?

Thanks

Anything is possible if you get creative. But it hasn't been designed with that purpose in mind.

I received the HSF Aeria bottle a couple of days ago. Installed it yesterday and it fits on my Dimond, barely, but it fits. No way it would have worked with the 70mm stem as it would not have cleared the Dimond's brake cover.

This looks pretty awesome...nice to see the computer mount moving forward....my preference is computer between the bar tips (learned from a st poster).....that way you can push buttons in aero and you can read it with the minimum movement of eyes from the road

No worries. How much does the hydration goes down below the stem?

This is the question I would like answered. From the bottom of the stem to the bottom of the hydration reservoir, what's the length?

I sort of wonder if there is any bike with a TriRig Omega X or any external brake that would accommodate this bottle when the bar is at or close to the lowest configuration.

Yep, me too.
Thinking about the bar/stem/hydration combo on my B10 with omega x.

No chance on your setup I would guess.

However, a flat kit or some such could be fashioned to hide the rest of your front end.

You know who to call for that.

Just yesterday, I received 2 of the hydration kits from Ceepo to go on my Viper-R frames. I have 2 of the bottles, but only 1 stem at the moment. The other stem is still to be shipped out. I mocked it up on my frame, and it looks good.

The stem is 100mm length, and rather heavy. The computer mount can be removed, and a second cover that's smooth fits in its place. The straw is big, and has a strong magnet to keep it folded down. The fill hole has 2 layers of star-slit-cuts to keep upspalsh down.

Happy to answer any questions.

Now that I finally have some of the bottles.
The unofficial answer to the question of "how low can you go with the HSF Aeria?"

The frame pictured has stack of 517mm, the headtube + headset cover is 110mm
The stem shown is the long (100mm) option

With a normal brake caliper




You can see that there is plenty of clearance vertically
The problem arises when we consider the caliper arm sticking out





It would be necessary to cut the gusset short of the head tube to provide clearance for the arm.
Could potentially fit on a slightly shorter headtube but would be a case of checking for a particular frame and caliper.
Would not fit with the 70mm stem at this height (arm would hit bottle).


Easier if we move on to centre routed calipers





The Magura would be beautifully hidden away. Once the gusset is fitted there would only be another 4mm clearance to the top of the caliper, so a 51cm NP2/3 or P5-Three would need a spacer under the stem to make it to 522 (as the absolute minimum) stack of frame +headset+spacers
Would not fit with the 70mm stem at this stack height


This image will likely not feature in the official fitting guide, but this mechanical centrepull caliper goes very nicely with the bottle.





Plenty of clearance. In fact you could go 20mm lower (probably, again this would require checking). Which brings it into scope for a 48 NP with a spacer under the stem.
Marginal on a 48 QR PR Series but good for a 50 (will not fit these sizes with a Shimano caliper)
Will it fit a 51 P4 with the steerer cut so short that you can't fit a spacer under the stem...No.


And finally - with the gusset on. Needs to be cut to match the headtube better. Will do that later.
Will attempt to put my bike together so I can field test too.

Perfect,thanx a lot for the effort to show it with different brakes.

Would love to see this mounted on a felt IAx..

Am I reading that the bottle fits better with the 100mm stem?

Do we know if much testing has been done on rough roads with these? I had a garmin bike computer go flying at frankfurt this year when my torhans mount snapped :(

That's probably bike and bike size dependent. As I mentioned earlier, the bottle would not fit on my bike if I had the 70mm stem. Dimond has a brake cover that protrudes out a fair bit and I barely clear it with the 100mm stem. My Dimond is a size M, which is equivalent to a L or 56 from other bike manufacturers.

Ah, I was hoping there was a cheaper option. Not sure the tri-rig is worth the $ since most of the aero goodness is hidden under the shroud. Wonder if a Campag rear TT brake could be configured to work? They're only ~$40.

Funny talking bout pricing of a brake while thinking bout a 150$ waterbottle.;-) (not to mention the stem or the bar)

---

-shoki

Well, I'm looking a the the stem/bottle combo as a possible cheap(ish) way to aerodynamically tidy up the front end of a basic tri bike. The fact that it holds water is just a bonus.

---

"They're made of latex, not nitroglycerin"

That bugs me too. Testing is limited so far but what has been done shows that the bottle is far more significant than the marginal gains from the centrepull caliper. So it makes a lot more sense to go with the bottle and a cheap brake that doesn't block the gusset. Unfortunately there aren't any cost effective front centrepull calipers now - I can't recommend putting rear brakes on the front in order to use PD product.

Will see if I can find a Transition to test on as that would answer the question in a safe way.

Probably the cheapest option in that case might be to place a regular bottle (Trohans aero 20/30;Profile....) there and tape a plastic sheet to it for a nice fairing to the steerer tube.
This can’t be called cheating anymore since the PD aeria ultimate bottle....cause it’s a none structural part, let’s call it fairing, right there.
The plus From the aero30 over the ultimate bottle from my POV is the weight is place a little lower and closer to the steerer.

---

-shoki

I'm not confident in your interpretation.

I mean, Gary p wants a none expensive aero option for the front
So why not using something like I said and tape the gap with some plastic or whatever to get the same result
I know to put something just for fairing is not legal BUT I don’t see any difference in this factory made fairing, got nothing structural as far as I see it in the pictures.

My bottle should arrive this week to test on a Neil Pryde 48cm, 100 Aeria Stem and TRP 860 brake.

Pretty much expecting it not to fit now

1) Suspect it would need 5mm more stack clearance from front tyre
2) bottle would found 860 brake with cable stop fit fitted. Might fit with 860 cover removed.

I've an Omega-X to solve 2).

A small shallower bottle with 1 cm less stack for 48 and 51 would mean they'll have coverage across pretty much every frame size. As the NP is about as low you can get without going to 650b wheels

Unfortunately that's not going to happen, they're so expensive to make that multiple sizes are not realistic.

Ive already been googling 'plastic hot knife' in anticipation of that!

I tried it on my Dimond but the magnetic cover of the Superfork will be in the way.

Do you still need the brake cover if you have the AU system though?

70 or 100mm stem. Yeah, no way it works with the 70mm stem but fits fine on the 100mm.

Do you know if there are any plans by PD to add tilt adjustability to the older Aeria Aerobar?

There is something on the way for later this year.

Do you know if this bottle set up would work with a p5-6 with the beard extending out beyond headtube or could it fit if you remove beard? Or maybe the gusset can essentially be a beard replacement?

Also does the bottle only need the Aeria stem for compatibility or does it also need to Ultimate Aeria Aerobar? I have regular carbon Aeria so if I bought the ultimate stem, would the bottle fit with that set up?

is that Enve stem not "slammable"?

Beard only works with Aduro bar/stem. Bottle only works with AU stem, so you can't have both. Not that you need both as shown below.
Astrid hadn't cut the gusset to match her head tube cleanly, she just has the brake covers, no beard.



You don't need the AU bar, just the stem. Which fits fine with original Aeria.

I can't tell. I'd normally put an RM10 on a cervelo. But it might be one of the chunkier models like RML

I took off 40mm to convert to pad x(rear)



To clear the TR brake on your size frame you really need the long stem, which is at the very limit of rearward adjustment for the above position (so it doesn't show in the results as the search is designed to not show extreme setups)
But can easily with your 480 Padx-centres

The stem fits, but I'm not liking the look of the clearance for the bottle with the nosecone.

Is that the 70mm or 100mm version?

Thanks!

Finally have the stem, bottle, and eTap blips/clics/wires and Torhans Bento X installed as best I can. Had to do some dremel work on the Dimond Aero Box to fit the clic/blip wires to guide them into the Bento X. The Blip Box is in the Bento X.

As far as I know, no online retailers have it right now. I had my local shop order it from PD or you can order on PD's website.

Hey fellow Dimond owner. I like the integrated bottle but you would be better with a true bta with the mantis position. The arms angled up with the gap filled force the air around the body but with your arms so wide the air will travel right through hitting the torso. I have just gone similar position myself so have been doing a lot of research. I am using a vision bta bottle that has a fill point right at the top that you can use when going mantis like position.

Alternately. Just get those arms shoved together. Looks possible to me with those parts.

That is the other option but comfort goes out the window IMO and a big part of finding best position especially for IM

Interesting. I have found the opposite in arms up. The closer, the better.

I'm squeezing my bta hard but not forearms together to close the gap. Each to their own...

Bottle out front is miles more aero, and then your arm position can be more flexible.

How have you tested this?

I'm not sure why I made the comment that I need to center my stem to the steerer better because the whole system moves as one then.

Yes, the bottle does aim more to one side. Which is going to make my math brain of symmetry and congruence go crazy.

---

Favorite Gear: Dimond | Cadex | Desoto Sport | Hoka One One

I've found this as well but I always go hands closer than elbows. Internal rotation helps greatly with shoulder discomfort.

More laps around a 3/8" mile oval race track than you can possibly imagine. I used to live about 2 blocks away and had a contact in the facilities team that would allow me to test any time it wasn't being used for something else. That was like 2005.

I don't know if I have replicated that test with Chung's VE method in Golden Cheetah. I have re-run most of my experiments that way.

Just to clear, by “bottle out front,” do you mean the profile aeria configuration, or a horizontal BTA setup (as opposed to a BTA angled upwards on sloping extensions)?

I mean if your extensions are steep (like 25%) in a mantis position, it's faster to put the BTA mount and bottle in front of the extensions rather than "on top". It blocks the same amount of air either way, but putting it out front essentially blends bottle to extensions to arms as a pretty nice leading edge.

Thanks for clarifying. Kinda the TJ config, I guess.

Yes, exactly.

Jesse Thomas is doing it now as well. His isn't the cleanest setup, but he's done some clever things.

Hi Dave

In my case, the hole through which you are running the front brake cable in that picture is partially obstructed by the head tube.

I suspect it will be OK if I was just putting the cable through without the black cable housing. What is the proper way to cable from the brake lever to this hole (with the thread) and throught the hole. Do I use a "noodle" of some kind ?

Any ideas ?

thanks

Can any of the owners of the hydration system chime in with the rough dimensions of it mounted on the stem. Would like to see if there would be a similar issue as the dimond owners seem to be having with the 70mm stem.

This issue with the Dimond is the brake cover. How many bikes have brake covers like the Dimond? As opposed to those with a much smaller profile that are somehow more integrated into the frame/fork like the Trek SC, Cervelo P5, Felt IA, Canyon Speedmax CF SLX?

I don't think the 70mm stem Aeria stem + HSF system would be an issue on a bike without a brake cover or with one that's part of the frame/fork. I haven't studied that though so take that with a grain of salt.

Hello, would anyone happen to know if I need to install the steertube compression plug to use the aeria ultimate stem? I am trying to install the stem but the compression plug will not fit inside the fork.

Mine didn’t fit either. I just used whatever plug I already had in there. Downside is you can’t use the stem cap cover as it bolts into the Aeria plug.

You don't have to use that plug. It's designed to fit with the top cap, so you'll just have to use a compression plug that works and a normal round top cap.

I wonder if they sent out a batch of wrong sized plugs. I have a 1 1/8" inch steerer and it didn't come close to fitting. My guess is the plug that came with the Aeria Ultimate stem was closer to 1 1/4". I even brought it to my LBS to get a second opinion that I wasn't retarded.

Curious what people think about the aero benefit of the bottle with more separation between bar and pads (like with pads pedestalled ~55mm)? (as opposed to just going with a standard BTA bottle set up)

Yes.

Dunno. My understanding is there are still aero benefits which come from the bottle lining up with frame.

Thanks -- and that's what I assume, curious about others trying it out. Appreciate getting to see the pics of how you have it set up-

was this done, does anyone how this setup compares aerodynamically to bta setup?

I picked up the stem + bottle. I am using it on my 54 P3 with a 3T aura bar using 40mm pedestals.

Major problem is refilling because the extensions are too close together to fit a bottle between and reach the hydration opening. I may have to invent something here to push the rubber splash protection apart so i can squirt into it without having to push it open with the bottle spout. I may eventually purchase the AU bar too because this is impractical.

I find that the straw opening is too small to drink efficiently from and I am going to cut it larger. I wish that there was a better way to tell how much fluid is left as well.

Just like everyone else, my brake does not fit nicely behind the beard. I am looking for a center pull brake that is cheaper than the tririg. In terms of space there is ample clearance between HT-bottle and bottle-tire.

Hi,

does anyone know the width of the hydration? If I were to use a Syntace Stratos CX ( https://www.syntace.de/...fm?pid=3&pk=3299 ) with PD Subsonic and Aeria Ultimate Stem - would that leave sufficient space between the extension to use the Aeria Hydration? If not, would "classic" PD Clip-Ons (not Subsonic) work (those Clip-Ons that position the extensions a bit further outward).

With "classic" Clip-Ons the available space between extension is 70mm. With subsonic I don´t know, but it could go down to 45 (80mm clamping area minus 2x 22mm).

What´s your take?

Thanks,
Tobi

The stratos CX would be marginal for fitting the Subsonic as the 80mm centre section may mean the clamp can't sit properly.

The HSF Aeria is 75.4mm wide

So to work with a Subsonic you need nearly 100mm extension width which means basebar clamp section 120mm (or a little more)

The Sonic bracket would have 90mm extension spacing on the Syntace bar thus 68mm between the extensions.
You need to have 100mm spacing between extensions (as that is what the Aeria Ultimate bar has and the bottle was designed around that) which means a clamping section width of at least 90mm with a Sonic or Supersonic bracket.

If you're using a J4 bracket you need 120mm clamp section.

Or if you have some risers under the bracket, this can all change.

Thanks for the reply - very helpful! At least Subsonic is now one option less to consider :-)

My plan is to convert my hybrid road/tri-bike (see attachment) to full tri and to clean up the cockpit while doing so. Though my front has a high stack (190mm) I still have approx 8cm drop to the pads which currently is OK for me. However by taking out the last 10mm spacer and switch to 17° stem (e.g. Aeria Ultimate) I could still go lower (should my body ever allow me ;-) ).

Cockpit-wize this leaves three options:

1. full integrated (e.g. Aeria Ultimate Stem/Bar/Hydration), Stem as low as possible and stack the armrests/extensions. This would put the hydration and gusset down, making it look clean. But does that really improve Aero as my arms (PLUS hydration!) are still above?
2. like option 1, but stack the stem so that the hydration is close to or even between extensions. Goal would be to hide the hydration from the wind and "expose" full steerer tube instead
3. conventional Flatbar (or 3T REVO) with Clip-Ons (e.g. Sonic) and BTA Hydration like PD FC/HC. That would be most flexible... and I am not sure if there really is an aero penalty.

If possible I want to avoid undermount, so 1. might even work without stacking the armrests.



Any thoughts? BTW, if this is too Off-Topic please let me know and I´ll move this topic to a new thread.

Thanks, Tobi

Any pics? I was planning to get the bottle but I also have Aura bars. Too narrow then?

I will take some photos this weekend. Are you using pedestal spacers?
