Zipp Super-9 Disc Center Lock SRAM XD-R Rear Wheel

Combining Zipp’s wheel laminate with a wider rim profile and optimized tire interface helps overcome the four barriers to speed: wind resistance, gravity, rolling resistance, and vibration losses. The result is less wasted effort. Optimal tire pressure is crucial to maximizing speed on the bike. To ensure proper inflation, the Super-9 comes with the TyreWiz 2.0 tire pressure monitor integrated out of sight, so you’ll always know if you’re in your desired PSI/bar range. Inflation is a breeze with redesigned pump access—no stickers needed.
