Zipp 858 NSW Carbon Tubeless Disc Brake Wheelset

Amalgamating all of the brand’s aerodynamic findings from the last 30 years with the latest materials and manufacturing techniques, the Zipp 858 NSW Carbon Tubeless Disc Brake Wheelset promises performance in any race against the second hand. Whether going for the podium in a regional age category triathlon or blasting across the course in a pro-level time trial, the 858 NSW delivers.

The full carbon rims comprise the finest carbon materials and resins to produce the highest lateral stiffness and strength with the lowest feasible weight. This refined material is encouraged into a radical, irregular, Sawtooth rim profile that promotes numerous Hyperfoil nodes along its inner circumference. This trailblazing format interacts uniquely with the oncoming air to markedly lower drag numbers and hugely increase crosswind stability. An intricate pattern of HexFin ABLC dimples and ridges complement this by inducing a slippery boundary layer of air across the surface of the rim to improve aerodynamic prowess further.

The rims feature a wider inner format that coerces tubeless-ready or standard clincher tyres into a refined cross-sectional silhouette. This honed form results in a shorter but broader tyre-to-road contact patch and increased tyre volume that, in turn, promotes lower rolling resistance, improved comfort and increased cornering grip.

Smooth-rolling and durable bearings are encased within the elegant Cognition disc brake specific hub bodies while the Axial Clutch freehub lowers resistance when freewheeling to help save energy. Reliable and strong Sapim CX-Ray spokes link everything together with 2-cross lacing patterns to complete the build with efficiency and reliability.
