Road cycling is evolving, so we keep innovating. The pursuit of AeroBalance™ defines Zipp’s approach to wheel design. Combining low drag performance with stable handling is our mission, because speed without control, is useless. Zipp’s NSW Series, since its inception in 2015, has been the launching pad for Zipp’s most relevant innovations. To that end, the Zipp 303 NSW Carbon Clincher features an entirely redesigned rim shape that aerodynamically integrates wider tubeless tires for enhanced ride quality and performance.
The 303 NSW Carbon Clincher Tubeless features a wider 19mm internal rim width and corresponding outer rim shape for aerodynamic optimization with 25mm tires. This wheelset allows you to run tubeless or traditional clinchers. The benefits of tubeless include superior flat protection, the ability to run lower pressures, and a smoother ride with high cornering grip and low rolling resistance.
