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. This wheel is optimized for 28mm tubeless tires for all out speed.

The 454 NSW features Zipp’s most advanced technologies. 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.

At the center of the 454 NSW is the Cognition V2 Hubset re-engineered with an updated Axial Clutch V2 mechanism for quicker engagement, lower friction, and improved durability.
