Zipp 303 SW Rear Wheel – 700 12 x 142mm Center-Lock XDR Tubeless Carbon w/ Wheel Sensor A1. Built for speed on any surface the Zipp 303 SW is your go-to wheelset for road gravel cobbles and cyclocross. It features Zipps integrated AXS Wheel Sensor letting you monitor tire pressure in real timeno valve-mounted devices needed. Check before you ride (green means go) and stay dialed in as conditions change. Inspired by the 303 XPLR the 40mm-deep rim uses a wide design for better aerodynamics and lower rolling resistance with wider tires. The result? A smoother faster ride with less fatigue. The improved carbon layup increases impact strength by nearly 10% while keeping weight low. Optimized for 3035mm tires (best with 35mm) the rim shape helps prevent pinch flats and improves tire-rim integration. At the core is the updated ZR1 hubset with stainless steel bearings for smoother longer-lasting performance.
