The S-Works Evade shares its roots with some illustrious company, namely, the fastest TT helmet in the world, the S-Works McLaren TT. When we set out to design it, we wanted to create a helmet that had all the aerodynamic benefits of a TT helmet, only without sacrificing fit or ventilation. The logical place to start was with the shape. If you place the Evade and S-Works TT helmet side by side, you’ll notice they bear a striking resemblance to one another. The Evade uses the same profile shape as the TT, which results in a drastic decrease in drag. How drastic? Compared to the S-Works Prevail, it saves you 46 seconds over 40km.
