Zipp 303 S Tubeless Carbon Front Wheel

Expanding greatly on its heritage of conquering the Spring Classics, this 303 S wheelset maintains its ideal-for-every-terrain with its 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 an entirely new rim profile and design to optimize rider performance on this new breed of bike. This wheelset is tubeless for disc-brake bikes, allowing the ability to run wide tyres at lower pressures for race-ready speed on or off the pavement.
