Overview

What Makes the Zipp 303 SW Fast on All Roads?

The Zipp 303 SW Tubeless Carbon Wheel is built for riders who want speed on all roads, no matter the surface. Its integrated AXS Wheel Sensor monitors tire pressure in real time directly through your SRAM AXS system, with no valve-mounted gadgets cluttering your setup. A quick pre-ride check confirms you are ready to roll. Inspired by the 303 XPLR, the 40mm-deep wide-profile rim improves aerodynamics and lowers rolling resistance for tires in the 30-35mm range, with a rim shape that helps shield the tire in an impact that would otherwise cause a pinch flat and gives an improved transition between rim and tire.

The revised carbon layup delivers an almost 10% improvement in impact strength at a light weight, making this a tougher, more confidence-inspiring wheel for mixed terrain. At the center is the updated ZR1 hubset with stainless steel bearings for smooth, long-lasting performance across road, gravel, cobbles, and cyclocross. Optimized for 30-35mm tires, the 303 SW is a single wheelset solution for riders who want race-ready performance everywhere they ride. Front and rear sold individually.
