The 303 S offers an entirely new rim profile and design to optimize rider performance. This tubeless carbon wheel is for disc-brake bikes, allowing the ability to run wide tires at lower pressures for race-ready speed on or off the pavement. The 303 S is among Zipp's lightest wheelsets, optimized for top aero performance with a 28 mm tire but capable of handling gravel tires up to 50 mm wide.
