I'm currently riding/racing on a Lazer Tardiz and from the threads I've been reading it appears that a new helmet may be some low hanging fruit for free speed. I've been trying to figure out which helmet to buy for this season. I plan on racing 1 IM, 1 70.3 and a handful of Oly distance races. I'm looking for something comfortable, not too hot and that won't leave my neck strained for days. Here are the ones that seem to be recommended based on google searching. I appreciate the help!
1. Smith Podium TT
2. Giro Aerohead MIPS
3. Lazer - Wasp Air, Tardiz 2, Victor
4. Kask - Bambino Pro
5. Louis Garneau LG P-09
6. Specialized S-Works
I have seen the Aerohead, LGP09 and Specialized get tested at the A2 tunnel on one rider. They were within .001 of each other
Then I saw the same 3 helmets on 2 world tour riders, outdoors with an aero device. Of those helmets, the Aerohead was fastest for one protour rider, the Sworks for the other.
Watch closely, you'll see Fuglsang with an Aerohead and a Spec as well as thweir sponsored helmet https://www.youtube.com/watch?v=nFkNp73Vvyw
