Zipp 303 S Carbon Clincher Disc Brake Rear Wheel

Zipp’s 303 S Tubeless Disc-brake wheels provides today’s cyclists the versatility they demand with the speed they crave. 

Expanding greatly on its heritage of conquering the Spring Classics, the 303 wheel maintains its ideal for every terrain 45mm rim depth but adds a significantly wider internal width to provide greater performance and ride quality in almost every measurable way. Road bikes are more versatile than ever, no matter the road surface, but just as fast as before. The 303 S offers a redesigned rim profile and design to optimise rider performance on this new breed of bike. This wheelset is tubeless for disc-brake bikes, allowing the ability to run wide tires at lower pressures for race-ready speed on or off the pavement.
