Zipp 303 SW Tubeless Disc-Brake REAR SRAM
Zipp’s 303 SW Tubeless Disc-Brake Wheelset is designed for speed across road, gravel, cobbles, and cyclocross riding. Its 40mm deep carbon rim uses a wide design for aerodynamic efficiency and reduced rolling resistance on wider tires at lower pressures. The wheelset is optimized for 30–35mm tires, with best performance with 35mm tires.
The rim integrates the Zipp AXS Wheel Sensor for on-bike tire-pressure monitoring, allowing riders to check and analyze tire pressure in real time without an external device mounted to the valve stem. The wide-rim design also helps reduce tire deflection and rider fatigue by combining increased tire volume with lower tire pressure. A revised carbon layup and design provide an almost 10% improvement in impact strength at a light weight. The wheelset features a ZR1 hubset with stainless steel bearings for improved durability and smoother performance.
