Zipp 303 SW Tubeless Disc-Brake Wheelset XDR
Zipp’s 303 SW Tubeless Disc-Brake Wheelset delivers fast performance across road and multi-surface riding, including road, gravel, cobbles, and cyclocross. Designed for modern riders using wider tyres at lower pressures, the 303 SW features a 40mm deep carbon hookless rim with a wide 25mm internal width. The wider rim design improves aerodynamic efficiency and reduces rolling resistance while increasing tyre volume and supporting lower pressures for a smoother ride over rough or imperfect surfaces. A revised carbon layup also provides nearly a 10% improvement in impact strength while maintaining a lightweight build.
The integrated Zipp AXS Wheel Sensor is built directly into the rim for real-time on-bike tyre-pressure monitoring. Riders can check pressure before a ride, with a green light indicating readiness, and monitor pressure while riding to fine-tune setup and detect issues early. The wheelset is optimised for 30–35mm tyres, with best performance at 35mm, and the rim shape helps shield the tyre during impacts that could otherwise cause pinch flats. At the centre is the ZR1 hubset with stainless steel cartridge bearings for improved durability and smooth performance.
