Zipp Rear wheel 454 NSW DISC Centerlock, TLR - Sram XDR

The Zipp 454 NSW Tubeless for disc brakes is the ultimate wheelset for road racing. This wheel delivers everything the performance-oriented cyclist demands. It is aerodynamically efficient and stable in all wind conditions. Additionally, a wider rim has been developed for tubeless tyres with lower pressure to reduce rolling resistance and vibration losses, so you lose as little energy as possible on the go. This wheel is optimised for 30 mm tubeless tyres for maximum speed. The 454 NSW features the most advanced technologies from Zipp. The wavy 58mm Sawtooth rim shape with Hyperfoils is our most aerodynamic and stable wheel. The 454 NSW incorporates Zipp's Total System Efficiency (TSE), our approach to combating the biggest speed adversaries: aerodynamic drag, gravity, rolling resistance, and vibration losses. The 454 NSW Tubeless for disc brakes is approximately one pound (over 400 grams) lighter than its predecessor! The use of hookless (straight) rims in the 454 NSW is a key part of “Making You Faster”. With Hookless, the transition between tyre and rim is smoother and more aerodynamic. The hookless rims from Zipp have a more efficient resin distribution, resulting in lighter and stronger wheels. An outdoor test commissioned by Zipp has demonstrated the benefits of the Zipp TSE in practice. A total system weight of 85 kg consisting of rider and bike requires 278 watts with the new 454 NSW with 30 mm tyres to maintain a speed of 40 km/h. That's a saving of 10 watts compared to the previous model 454 NSW. At the heart of the 454 NSW is the Cognition V2 hubset, which has been revised with an updated Axial Clutch V2 mechanism for faster engagement, lower friction, and improved durability.
