Throughout Zipp's 30-year history, its pursuit has been speed, with a passionately focused mindset "…to make you faster." With aerodynamics reaching a natural plateau of performance progress, Zipp ushers in a new era with the 303 S carbon wheel that looks beyond air resistance to boost efficiency across the entire wheel-system, giving us "the next chapter of speed." Designed to match with our modern drop-bar bike's increasingly ample frame clearance and the real-world challenges, like gravel washboards and infrequently paved back-roads, the 303 S works to preserve our energy so we can make speed. 
Endurance and performance lines converge in the all-new design
Aerodynamically optimized for road, but can run wide gravel tires
Decreased weight improves responsiveness and steep-slope speed
Updated graphics are asymmetrical and eye-catching
Tubeless compatible tire only
Zipp continues to expand the capabilities of the modern wheelset
