Zipp 303 S Carbon Tubeless Disc Brake Center Locking 700c

SPEED FOR ALL ROADS AHEAD

The Zipp 303 S Series Tubeless Disc Brake wheelset provides today’s cyclists with the versatility they demand and the speed they crave. Expanding on its heritage of conquering the Spring Classics, this wheelset maintains an ideal-for-every-terrain 45mm rim depth while introducing a significantly wider internal width to provide greater performance and ride quality in almost every measurable way. Road bikes are more versatile than ever, and the 303 S offers an entirely new rim profile and design to optimize rider performance on this new breed of bike, no matter the road surface.

This wheelset is purpose-built for tubeless disc-brake bikes, allowing riders to run wide tires at lower pressures for race-ready speed on or off the pavement. As one of our lightest wheelsets, the 303 S is optimized for top aero performance with a 28mm tire but remains capable of handling gravel tires up to 50mm wide. By borrowing design concepts from the higher-level Firecrest series, it gains speed through increased efficiency, reducing wind resistance, rolling resistance, rider fatigue, and weight.

The key innovation lies in the hookless rim design. The 23mm internal tire bed is designed to be fastest with a 28mm tire, optimizing the tire profile to allow lower pressures. This reduces rolling resistance and provides a more compliant ride. Internal testing shows a 10 percent watt savings versus a top peer wheel in total power required to ride 40kph on a smooth flat road. These wheels also feature striking graphics that set you apart from the pack while delivering groundbreaking technology at an attractive price.
