Zipp’s 454 NSW Tubeless Disc-brake is the ultimate road racing wheelset. This wheel delivers everything the performance cyclist demands. It’s aerodynamically efficient and stable in all wind conditions. What’s more, a wider rim is designed for tubeless tires at lower pressure for reduced rolling resistance and vibration damping, so you’ll lose as little energy as possible out on the road. For the best combination of aerodynamics and rolling resistance gains a 28mm tire is recommended on this wheel. Its undulating 58mm Sawtooth rim shape with Hyperfoils is our most aerodynamic and stable wheel. The 454 NSW features Zipp’s Total System Efficiency (TSE), our approach at combatting the biggest enemies of speed: wind resistance, gravity, rolling resistance, and vibration losses. And gravity? Zipp’s use of hookless (straight side) rims in the 454 NSW is integral to Making You Faster. With hookless, the transition between the tire and the rim is more seamless and aero. Zipp’s hookless rims have more efficient resin distribution, which means lighter, stronger wheels. The 454 NSW features the premium ZR1 SL hubset with ceramic bearings and 66 points of engagement. The hubset also is 30 g lighter than the predecessor hub in NSW wheels.
