Zipp 303 SW Carbon Tubeless Disc Brake 700C B1

Zipp’s 303 SW Tubeless Disc-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. This system is designed for the modern rider who demands high performance across diverse terrain.

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 you are ready to roll. During the ride, monitor pressure to dial in your ideal setting and detect issues early.

The 40mm deep rim design utilizes a wide profile for high aero efficiency and low rolling resistance on a wide tire platform. The rim’s profile provides low drag and an improved transition between rim and tire, boosting aerodynamic efficiency. Combining Total System Efficiency (TSE) with increased tire volume 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 also provides an almost 10 percent improvement in impact strength while maintaining a light weight.

At the center of the wheelset is the ZR1 hubset, which features stainless steel bearings for improved durability and smoother performance. The 303 SW is optimized for tires 30 to 35mm in width, with a refined shape that helps shield the tire in an impact to prevent pinch flats.
