okay. I'll be interested. I have the P9. Not that I'm a speedster but if it actually was something like 10 watts that seems significant. I'm probably fine with the P9. I like the looks of the aerohead better.

Helmets is one of those things that is very individual regardless. Without actually testing in the wind tunnel, field testing etc, it is just dart throwing. The P9 was the helmet that tested fast on a lot of people which is why I went with originally - this was many years before the Aerohead. The Aerohead is testing faster now than the P9 for the majority of people. It is solid recommendation suggesting the Aerohead. You might be wrong occasionally, but you are going to be more right than wrong over the long run.

You're fast enough already, just buy it. It's a gorgeous helmet.

Thomas, did you say you had a small giro and a medium LG?
I have a medium p09 and wondering if I should get a small aerohead.

That's part of my issue with the aerohead; fit around the nose. It is so well fitted that it surrounds my nose to the point I can't farmer blow! Haha. Or, I can but it blasts back inside the visor. The constant post ocean swim drip isn't fun.

The aerohead visor is handy to have flipped up in transisition, and also useable on long hills...flip it up and start climbing!

I have a tweener head. I wonder if I could fit a small p09 as well. The medium given it is large size and heavy weight I found myself having to ratchet the dial down as far as it would go and then it would still move. I am getting crazy light as well, much lighter than last year so I am not sure how much that has to do with it. Regardless, when I bought the medium it was the only helmet available on day 1 and that is what I bought. I have a medium as well that I have to now sell. But yes, the small is very small. It is a tight squeeze.

Well it is a fine looking helmet that's for sure.

I think the p09 is way better looking, but I owned one and did not find it comfortable.
I do find the cerebel comfortable, but may just go with a Scott cadence this year. I'm MOP and 30 seconds here or there won't matter.
The Smith looks cool, but over 400+tax here in Canada...

Any tunnel updates on the Podium?

I am scheduled to go in next Wed., promise to provide the results!

And I am back from the tunnel! I will post the data when I have it but the Smith Podium tested 25g less drag for me then the Aerohead.

can't wait to hear the info...I have a new Podium ready to dance!

@thomasgerlach - Take this into the aero tunnel for real!

I just recently bought a POC and will be doing my first races with it next weekend. So far I havent dont a long enough ride to really tell you much. But I will say if you look down while in aero position sometimes the wind will catch the vents and make a howling noise.

Nice giro ripoff. I bet it is decently fast, especially if you tape the vents.

I agree with the P9 not being particularly comfortable. Not terrible but I don't like it on the ears. I got the Giro Aerohead on the recent CleverTraining 20% discount. I've only tried the Aerohead on but it feels more comfortable since the shield wraps around and nothing is closed close to your ears. I'm taking the Aerohead for a ride this weekend.

Hmm, maybe I should pull my Podium back off the classifieds. My head is a little taller than average and I just felt like the ear flaps could have come down a little lower than they do on the Podium. It's not like my Javelin where everything is all-in.

OK, here are the results. They are VERY close so you likely can't go wrong with either but we do have a lot more individual testing results on the Giro then the Podium. Even Aaron at FASTER has seen the Aerohead test very well for a lot of different riders.

Thanks for the follow-up!

Even though everything is super individual, it's nice to know that the Podium is likely not a brick in the aero world. It's a gorgeous helmet and the lenses are superb.

Have you ever tested with a Cerebel?
I think the Smith looks great, but as the above poster mentioned, I'm not sure I'd be happy with it not coming down all the way over the ears. The Cerebel goes all the way over the ears..

I've ordered a POC. I was a little ambivalent because I feel my Bontrager Ballista is doing a fine job in race, though the ventilation, in my opinion, isn't amazing (compared to a, say, Sworks Prevail helmet), paired with some Oakley EVZero Path glasses. My primary interest is better visibility. Even though the EVZero's are rimless, with my head pretty low, I have to position the glasses just right and if I hit a bump, they slip a tad. A helmet with a visor may allow me to keep my head low in a manner that I hope will feel safer.

thoughts with regard to visibility with the POC vs standard helmet and glasses?

Thanks for posting. My eyeball WT says you appear to look down quite a bit so your position doesn't do the Aerohead any favors. I think the Aerohead is more effective when the airfoil shape of the visor is more exposed to the wind. With your position the visor is mostly hidden behind the brim of the helmet. I would guess the Kask and POC would also work well on you.

Funny enough I train wearing my Ballista and a pair of EV Zeros and experience the same thing. I often end up having the edge of the glasses be right where I'm trying to look (truth be told I can actually see the a bit of the leading edge of the helmet too).

I don't recall how the POC fared specifically (I'm away from home otherwise I'd go check for you) but the visibility from my Aerohead is superb.

yep, the front edge of the Ballista obstructs my vision a tad; I have to position it tilted back a tad. I'm hoping the POC Cerebel resolves those issues.

Chiming in with my n = 1.

Coming from S-Works TT. Fit was a little bit too loose/wrong shape for my head so it would rotate forward into my vision during the race. Ordered the Aerohead and Podium. Aerohead had similar loose fit to S-Work TT, Podium fit perfectly. Love Smith ski helmets and googles, they always fit well. Podium TT helmet is no different. Excellent visor too. Raced the Podium last weekend, hot and humid but it was a surprising cool helmet. Best compliment a helmet can get in my mind is that you forget about it, which the Podium certainly achieved. It makes a slight whistle when you stick the tail up but that was a perfect reminder to keep the head down.

I'm happy with it and would recommend as a worthwhile try on. $100 more than the Aerohead but comes with two visors, case and Smith warranty.
