Zipp Super-9 Disc Rear Wheel – 700 12 x 142mm Center-Lock XDR Black B1. Thanks to Zipps Total System Efficiency (TSE) carbon laminate and design the Super-9 is engineered for a new era of wider tires and lower tire pressure in TT and triathlon. Combining Zipps wheel laminate with a wider rim profile and optimized tire interface helps you overcome the four barriers to speed: wind resistance gravity rolling resistance and vibration losses. The Super-9 is fastest with 28mm tubeless tires inflated to lower than traditional pressure. To ensure proper inflation the Super-9 comes with the TyreWiz 2.0 tire-pressure monitor integrated out of sight and perfectly balanced so youll always know if youre in your desired PSI/bar range. Inflation is a breeze with redesigned pump access. Moreover the disc features a redesigned pump-access portno stickers needed. The Super-9 features the premium ZR1 hub with ceramic bearings and 66 points of engagement.
