Aerodynamic helmet

Which is the most aerodynamic helmet? And I'm not talking about TT-helmets, i'm talking about like the S-Works Evade and the Air Attack.

You'll have to test them all on yourself to find out which one is most aerodynamic FOR YOU. They could all have the same cDa, but because of how the air interacts with the helmet and the body of the rider, there are influences that could raise or decrease that drag figure. All helmets will interact differently on the same rider, therefore you would have to find out which helmet/you combination is most aerodynamic.

If you ask me, I don't think it matters. Get the one that fits your head properly. If you're a good enough rider that one of these helmets matters, then you will be supplied with one by your sponsor.
