Depending upon the day, both Quickstep-Floors and Bora–hansgrohe decide between the S-Works Evade and the S-Works Prevail II. And while the aerodynamics of the new Evade often rule the roost, when the mercury begins to bubble, the Prevail II is the best option. It’s cooler than not wearing a helmet, and still features an aerodynamic benefit that most lightweight helmets lack. And yes, both have helped in racking up stage wins this year.
