The Zipp Super-9 Disc Centerlock is an ultralight, aerodynamic carbon rear wheel for triathlons and time trials. Thanks to its hookless tubeless design (23mm internal width), the wheel is optimized for wider tires and low pressure, resulting in minimal rolling resistance and maximum speed. Equipped with a ZR1 hub with ceramic bearings, an integrated TyreWiz 2.0 tire pressure gauge, and a Centerlock disc brake mount. Perfect for those seeking top performance.
