Zipp 858 NSW Wheel

The undulating Sawtooth rim profile with Hyperfoil nodes is designed to shed wind vortices more effectively than a standard deep-section rim. This creates a more predictable and stable handling experience, allowing you to stay in your aero position even when wind conditions are gusty or unpredictable.

The Zipp 858 NSW features a hookless rim design, which is specifically engineered for tubeless-ready tires. You must use tubeless-compatible tires with this wheel, and it is important to verify that your specific tire model is approved for use on hookless rims.

Ceramic bearings are harder, smoother, and more durable than traditional steel bearings. In the ZR1 SL hub, they reduce rotational friction, which helps maintain your momentum and ensures that the power you put into the pedals is transferred to the road with minimal energy loss.

This specific model comes equipped with a SRAM XDR freehub body. If you are running a Shimano drivetrain, you will need to swap the freehub body to a Shimano-compatible version before installation.

The wider 23mm internal profile allows you to run lower tire pressures, which increases the tire's contact patch with the road. This setup improves grip and comfort while reducing rolling resistance, making the wheel faster and more compliant on varied road surfaces.

While the 85mm rim depth is optimized for maximum aerodynamic efficiency on flat to rolling terrain, the advanced carbon construction keeps the weight competitive for its size. However, if your ride involves significant climbing, you might find a shallower rim profile more responsive and easier to handle.
