Zipp 858 NSW 700c Road Wheel – Rear
When you want the fastest rear wheel in the game, this is it. The Zipp 858 NSW rear wheel is engineered for those who demand maximum aero gains, minimal rolling resistance, and no compromise in speed—whether you’re tearing through a time trial, hammering a triathlon, or slicing through road stages with surgical precision.

Speed Meets Stability
The wave-like 82/85mm SawTooth™ rim profile paired with HexFin™ ABLC dimples delivers unreal aerodynamic performance while keeping the wheel stable in crosswinds. With a 23mm internal width, it’s optimized for 28–32mm tubeless tires, allowing for lower pressures and better rolling efficiency. Less fatigue. More watts saved.

Built to Perform and Last
A ZR1 SL hub sits at the core, featuring lightweight alloy construction and ceramic hybrid bearings for ultra-smooth rolling. The freehub's 6-pawl design delivers 66 points of engagement for immediate power transfer. Add in disc brake compatibility and a hookless tubeless setup, and you’re looking at a serious performance upgrade.
