Zipp 303 Firecrest Tubular Rear Wheel 24 Spokes 10/11 Speed SRAM Cassette Body - Black Decal 2015

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.

The 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.

At just 1,335 grams, the weight of the new 303 is virtually unchanged from its predecessor and remains one of the lightest carbon wheelsets anywhere. Its 45 mm-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.
