454 NSW Tubeless Disc-brake wheels are the ultimate choice for road racing, delivering everything the performance cyclist demands. The design fuses two of Zipp’s most advanced approaches; the Sawtooth rim profile and TSE, for an all-encompassing approach to performance. At the center of the 454 NSW is the Cognition V2 Hubset, re-engineered with an updated Axial Clutch V2 mechanism for quicker engagement and lower friction as well as improved durability.

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.

Zipp’s 858 NSW wheels are now faster than ever, thanks to their Total System Efficiency (TSE) technology. This design includes a tubeless, hookless rim that reduces weight and creates a smooth fit with the tire. Despite having deep rims, the 858 weighs as little as much shallower wheels. Its 23mm internal width is ideal for wider tires run at lower pressures, which helps reduce rolling resistance. TSE technology addresses four key speed barriers: wind resistance, gravity, rolling resistance, and vibration. The rim’s unique 85mm depth and patented Sawtooth shape improve aerodynamic performance and stability in crosswinds, making it perfect for triathletes, time trialists, and speed-focused riders. While it’s optimized for tubeless tires, it also works with tubeless-ready tires and tubes. It performs best with a 28mm tire, and using wider, lower-pressure tubeless tires not only increases speed but also smooths the ride, helping athletes stay fresher for the run. Disc brakes provide strong, reliable stopping power in all weather conditions, and the wheel includes Zipp’s high-performance ZR1 SL hubs with ceramic bearings for reliable use.

Zipp’s ultimate aero weapon is faster than ever, thanks to their proprietary Total System Efficiency technology. With TSE, the 858 NSW Carbon Tubeless Disc-brake wheels features a tubeless and hookless rim profile for seamless tire interface and huge drop in weight. The wheel’s internal width is 23mm, ideal for running wider tires with lower pressures for decreased rolling resistance, and the Carbon Internal Reinforcement (CiR), creates a rim that is 10% lighter and just as strong as previous wheels. At the center of the 858 NSW is the Cognition V2 Hubset engineered with the Axial Clutch V2 mechanism for quicker engagement and lower friction as well as improved durability. The result is pure speed, especially for triathletes, time trial specialist, and any other speed freak.
