Zipp 454 NSW Rear Wheel - 700 12 x 142mm Center-Lock XDR Tubeless Carbon C1

Zipp 454 NSW Rear Wheel - 700 12 x 142mm Center-Lock XDR Tubeless Carbon C1. The 454 NSW is Zipp’s top-tier road racing wheelset—built for speed stability and efficiency. Its 58mm Sawtooth rim with Hyperfoils offers unmatched aerodynamics and handles well in any wind. Designed for tubeless tires the wider hookless rim allows lower pressure for less rolling resistance and more comfort. Pair it with a 28mm tire for the best balance of speed and ride quality. Zipp’s Total System Efficiency (TSE) tackles key performance killers: wind weight rolling resistance and vibration. The hookless rim design also makes the wheel lighter and more aerodynamic by creating a smoother tire-to-rim transition.The 454 NSW rolls on Zipp’s premium ZR1 SL hubset with ceramic bearings and 66 points of engagement—now 30 grams lighter than the previous model.
