On the market for a tt aero helmet!
I have a old Lois garneau rocket small! bought a giro aerohead small and it’s not comfort to me! The visor squeeze my ears too much!!! I was think going to P-09.
What do you use ? Any advice?
Thank you!

If you want the simplest possible answer of "go buy this" with no testing and us not being provided any information...........just go spend your cash on a Giro Aerohead and we can close the topic.

The question is really pointless without the context of photos or videos of bike fit.

This is such a personal topic. It spans budget, body position on the bike, race demands like temperature and distance, etc.......

My best advice to you is to first post back with what your target races are. How far, how hot might they be. Then post up a photo of your bike fit. Then just maybe, folks could give a few to try.

After that, you still don't know.

I've owned 4 different lids in a year and tested in the field 6 including road helmets. This took a lot of time. But, so far it has yielded me nearly 10w free. And that's not to say I don't need to try more.

So..........that's really the journey. It isn't just an open ended question of "what should I buy".

Not everyone has spent a lifetime on ST and knows what questions to ask. Be kind.

Also, if you read the OPs post, they literally said they tried the Aerohead and it wasn't comfortable. Then you went on and suggested the Aerohead. Lol

To OP, since the Aerohead didn't work for you, maybe take a look at the POC and P-09. I believe both are fast for many, and they all fit very differently. But if you can figure out how to test them, do that.

Hey there, thanks for your reply - which POC do your recommend for an aero'ish helmet?

@desertdude -

How much faster would you say the Giro Aerohead is against, say an 'average' aerodynamically shaped helmet?

I'm going around in circles and can't decide between an aerohead or codatronca.

Please please please can someone talk me into one or the other? Concerns with the aerohead is everyone seems to complain how heavy it is. But also regularly is mentioned as being the fastest.

There is little info on the Codatronca but seems it might be the better option?

If you're in the US, the MET Codatronca isn't CPSC-approved so you can't buy them in the US or use them in USA Triathlon sanctioned races. Also doesn't have MIPS, if you care.

Do they ever check/care? I've never had anyone look at my helmet? Maybe just been lucky?
