Zipp 303 SW Carbon Wheelset - Wheel Sensors Included

Zipp’s 303 SW Tubeless Disc-brake wheelset delivers fast performance across all road and multi-surface riding, including road, gravel, cobbles and cyclocross. Built on Zipp’s legacy of innovation, the 303 SW is a modern classic designed for modern riders running wider tyres at lower pressures.

A key highlight is the integrated Zipp AXS Wheel Sensor, built directly into the rim for accurate on-bike tyre-pressure monitoring in real time. This allows riders to monitor and analyse tyre pressure without an external device mounted to the valve stem. Before a ride, pressure can be checked instantly (green light indicates ready to ride), and during riding, pressure monitoring helps fine-tune setup and detect issues early.

The 303 SW features a 40mm deep carbon hookless rim with a wide 25mm internal width, taking design cues from the gravel-specific 303 XPLR. This wider rim design improves aerodynamic efficiency and reduces rolling resistance, providing a smoother ride over rough or imperfect road surfaces by increasing tyre volume and supporting lower pressures. A revised carbon layup further improves durability, delivering nearly a 10% improvement in impact strength while maintaining a lightweight build.

Optimised for 30–35mm tyres (best performance with 35mm tyres), the rim shape also helps shield the tyre during impacts that could otherwise cause pinch flats. At the centre is the ZR1 hubset, updated with stainless steel cartridge bearings for improved durability and smooth performance.
