Zipp 303 SW wheelset with pressure sensor

Zipp 303 SW ZR1 40mm Disc Tubeless-Ready Carbon Cycling Wheels with AXS 2025 Pressure Sensor

The Zipp 303 SW - WH-303-SW-A1 wheels are designed to deliver high-level performance on all types of terrain, from road to gravel, including cobblestones and cyclocross. Zipp integrates AXS innovation into this model with a tire pressure sensor directly integrated into the rim, allowing precise and real-time pressure monitoring, without external accessories on the valve.

Connected performance with the AXS sensor

Zipp equips the 303 SW rim with the internally integrated Zipp AXS Wheel Sensor. This system analyzes and monitors tire pressure in real time, helping optimize performance in a variety of riding environments. Before each ride, a green light indicates whether the pressure is adequate. While riding, the rider can monitor pressure changes to adjust settings or detect problems quickly.

Aerodynamic and comfortable design

The 40mm deep rim profile is inspired by the Zipp 303 XPLR gravel model. It adopts a wide shape, designed to improve aerodynamics while reducing rolling resistance. This design promotes a smooth transition between the rim and wider tires, optimizing speed and comfort on rough or uneven roads.

Thanks to reduced tire deformation and better vibration absorption, this rim-tire system limits rider fatigue. The combination of a larger tire, lower pressure, and increased air volume allows for a smoother and more efficient ride.

Improved robustness and modern compatibility

The Zipp 303 SW wheels ' carbon structure has been reworked to improve impact resistance by nearly 10%, while maintaining a low weight. The model is optimized for 30-35mm tires. The rim shape effectively protects the tires in the event of an impact that could cause a pinch flat.

The ZR1 hub, positioned in the center of the wheels, is now equipped with stainless steel bearings for increased durability and a smoother ride.
