Zipp 303 SW Rear Carbon Tubeless Disc Brake 700C B1

The Zipp 303 SW Tubeless Disc-brake wheelset delivers superior speed across every surface, from smooth pavement to rugged gravel and cyclocross courses. Built on a legacy of innovation, this modern classic is designed for the demands of contemporary riding, offering a perfect balance of aerodynamic efficiency and all-road versatility.

This wheelset features an integrated AXS Wheel Sensor for accurate, real-time tire pressure monitoring via the SRAM AXS app. By allowing riders to fine-tune and analyze pressure without external devices, it ensures optimal performance in ever-changing environments. The 40mm deep rim design utilizes a wide internal profile for high aero efficiency and low rolling resistance, specifically optimized for modern riding at lower tire pressures.

The wide-rim stance reduces tire deflection and absorbs road vibrations, smoothing out the ride over imperfect pavement to significantly reduce rider fatigue. With a revised carbon layup, the 303 SW offers an almost 10 percent improvement in impact strength while maintaining a lightweight profile. At the center of the wheel is the ZR1 hubset, now featuring stainless steel bearings for improved durability and smoother performance in all conditions.
