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 gravel, cobbles, and cyclocross. Built on a legacy of innovation, the 303 SW is a modern classic designed for riders running wider tyres at lower pressures to achieve maximum efficiency and comfort.

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 pressure without an external device mounted to the valve stem. Before a ride, pressure can be checked instantly via the indicator light, and during riding, monitoring helps fine-tune your setup and detect potential issues early.

The 303 SW features a 40mm deep carbon hookless rim with a wide 25mm internal width. This design improves aerodynamic efficiency and reduces rolling resistance, providing a smoother ride over rough surfaces by increasing tyre volume. A revised carbon layup further improves durability, delivering a 10% improvement in impact strength while maintaining a lightweight, agile build. At the centre is the ZR1 hubset, featuring stainless steel cartridge bearings for improved longevity and smooth performance.
