ZIPP 454 NSW Tubeless Disc B1 Rear

The ZIPP 454 NSW Tubeless Disc B1 Rear is the back half of 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 best combination of aerodynamics and rolling resistance gains, a 28mm tire is recommended on this wheel. While 25mm tires offer a small aerodynamic gain, the losses in rolling resistance from a 28mm tire outweigh the aero gain. Therefore for best performance ride a 28mm tire. The ZIPP 454 NSW Tubeless Disc B1 Rear features Zipp’s most advanced technologies. Its undulating 58mm Sawtooth™ rim shape with Hyperfoils™ is Zipp's 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 ZIPP 454 NSW Tubeless Disc B1 Rear 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. At the center of the ZIPP 454 NSW Tubeless Disc B1 Rear is the Cognition V2 Hubset re-engineered with an updated Axial Clutch V2™ mechanism for quicker engagement, lower friction, and improved durability.
