Zipp 303 SW A1 700C Rear Wheel 12x142

The Zipp 303 SW A1 700C rear wheel is an ultra-versatile wheel designed to offer superior speed on all surfaces , from road to gravel, including cobblestones and cyclocross. A true "do-it-all" wheel, it combines aerodynamics, efficiency, and comfort.

Its wider rim profile improves the transition between the rim and the tire, reducing aerodynamic drag and increasing efficiency with wider tires. The increased rim width limits tire deformation, which decreases rolling resistance and improves overall performance.

Optimized for 30-35mm tires (maximum performance at 35mm), the 303 SW allows for lower tire pressures , increasing air volume and reducing rider fatigue on rough roads. Its refined rim shape protects the tire from impacts to minimize the risk of pinch flats.

Equipped with the integrated Zipp AXS sensor , it offers precise, real-time tire pressure monitoring. The ZR1 hub ensures reliability and efficient engagement, all covered by a lifetime warranty .
