Zipp’s original 303 Tubular made history by becoming the first carbon wheelset to win cycling’s two most famous Cobbled Classics, Paris-Roubaix and the Tour of Flanders. Its wider rim provided extra durability, and improved aerodynamics. That wider rim also led to the development of our revolutionary Firecrest® platform, and now the revolution continues with the inclusion of the 77/177 hubset – with best-in-class durability and improved bearing protection with no pre-load adjustment needed.
Optimized flange geometry and spoke hole attachment pattern with Sapim CX Sprint spokes to optimize torsional and lateral stiffness and robustness.
Includes newly designed quick-release skewers with a wider more ergonomic handle to provide more leverage for opening and closing. When closed, lever contours neatly with the frame. There is also the introduction of a new robust hub platform with distinctive graphics.
Zipp’s Carbon Clincher technology preserves the aerodynamic advantages of the 303 Firecrest’s tubular brother, while adding the convenience of a clincher tire.
The Firecrest shaping optimizes the aerodynamic profile of both the front half and the back half of the wheel. In addition, Firecrest moves the centre of pressure of the wheel backwards, giving the 45mm deep rim the crosswind stability of a box-section rim. At the same time, the 26.4mm wide brake track (at centre) allows the clincher tire to take on a wider, more stable shape without compromising rolling resistance. It’s faster, simpler, and more stable.
The new wheels retain all the small details that make Zipp wheels what they are. Exposed spoke nipples sit in the aerodynamic shadow of the rims, keeping serviceability simple without compromising speed. And our signature ABLC™ rim dimples squeeze every last second of performance possible.
Each 303 Firecrest Carbon Clincher wheel comes with Tangente Platinum Pro Evo brake pads, Zipp Integrated Valve Extender with valve-core wrench, rim tape and quick release. Zipp wheels are sold separately (front wheel and rear wheel) by Pushy’s, and do not come as a wheelset.
