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, but it won the two biggest classics of them all: 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 introduced last year. And now that development has come full circle, as we introduce the 303 Firecrest. The all-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.

Firecrest Revolution

At just 1198 grams, the weight of the new 303 is virtually unchanged from its predecessor, and remains one of the lightest carbon wheelsets anywhere. Its 45mm-deep rim outperforms much deeper rims with a traditional v-shaped cross-section. And yet, because Firecrest technology allows us to manipulate the wheel’s center of pressure, the new 303 handles like a box-section rim. It's ultra-stable, and suitable for even the windiest days.
