Zipp 454 NSW Tubeless Disc Wheels

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 25mm 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™), their approach at combatting the biggest enemies of speed: wind resistance, gravity, rolling resistance, and vibration losses. And gravity? The 454 NSW Tubeless Disc-brake is roughly a pound (more than 400 grams) lighter than its predecessor! Zipp’s use of hookless (straight side) rims in the 454 NSW is integral to Making Y
