Zipp 303 SW Rear Wheel - 700 12 X 142mm Center-Lock XDR Tubeless Carbon W/ Wheel Sensor A1 Carbon 700c

Season:2025

Brand:Zipp

Code:WE3486

Zipp's 303 SW Tubeless Disk-brake wheelset offers superior speed on all roads, no matter the surface. Steeped in Zipp's legacy of innovation, the 303 SW is a modern classic wheelset, fully capable of road, gravel, cobbles, and cyclocross riding.

The 303 SW rim internally integrates the Zipp AXS Wheel Sensor for accurate on-bike tire-pressure monitoring. It allows you to monitor and analyze 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. Before you ride, check your pressure immediately; a green light means good to go. During the ride, monitor pressure to dial in your ideal setting and detect issues early.

The 303 SW's 40mm deep rim design takes design cues from the gravel-specific 303 XPLR to utilize 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 wide-rim stance also features less tire deflection for reduced rolling resistance. Combining the wider tire, increased tire volume, and lower tire pressure helps reduce rider fatigue by smoothing out the ride over imperfect pavement and road conditions—the tire and wheel system absorbs the shaking, not the rider.

A revised carbon layup and design also infused the already bombproof 303 SW with an almost 10 percent improvement in impact strength at a light weight. The 303 SW is optimized for tires 30 to 35mm in width, with the best performance with 35mm tires. The 303 SW rims feature a refined shape that helps shield the tire in an impact that would otherwise cause a pinch flat. At the center of this is the ZR1 hubset, which now has stainless steel bearings for improved durability and smoother performance.
