The 303 is a wheel you can never count out. In 2010, it became not only the first carbon wheel to win a major cobbled classic, it won the two biggest classics: Paris-Roubaix and the Tour of Flanders. The wheel is light, utterly dependable and aerodynamic. And it’s just gotten even better.
Our exploration of the 303’s wider rim led to the Firecrest® technology. And now that development has come full circle with the 303 Firecrest. The new wheel features Firecrest’s signature shaping designed to optimize both halves of the wheel, which creates a rim that is significantly faster and also much easier to handle in crosswinds.
