303 SW Carbon Disc Wheel - 700c

The 303 SW rim internally integrates the Zipp AXS Wheel Sensor for accurate on-bike tire-pressure monitoring, allowing you to monitor tire pressure in real-time without an external device mounted to the valve stem. Fine-tuning tire pressure helps riders optimize speed and performance in an ever-changing riding environment.

Check your pressure immediately before your ride, and during the ride, monitor pressure to dial in your ideal setting and detect issues early.

The 303 SW’s 40mm deep rim design utilizes a wide rim design for high aero efficiency and low rolling resistance on a wide tire platform designed for modern riding at lower tire pressures.

The rim’s profile provides low drag and an improved transition between rim and tire, boosting aerodynamic efficiency with wider tires.

The 303 SW is optimized for tires 30 to 35mm in width.

A revised carbon layup and design infuses the already bombproof 303 SW with a near 10 percent improvement in impact strength at a lighter weight. The 303 SW rims feature a refined shape that helps shield the tire from impacts that would otherwise cause pinch flats. At the center of the wheels is the ZR1 hubset, which now has stainless steel bearings for improved durability and smoother performance.
