Zipp 858 NSW Clincher Disc DB Rear Road Wheel

The Zipp 858 NSW Carbon Clincher Disc Brake wheel design is based on the exceptional performing Zipp 454 NSW wheelset and features an optimised design, which provides the highest-level of deep rim performance in this category. Featuring a rim depth of 77mm, which slices through the air and effectively reduces air-drag. Unlike most other competitors wheel options in this wheel depth, the 858 NSW features exceptional crosswind stability and precise handling thanks to the Zipp Sawtooth and Hexfix technology. Exceptional Rolling Performance & Stability This wheel is also equipped with the Cognition Disc hub, it has all the rolling performance and stability enhancements of wheels that have a much shallower profile, and now the braking excellence of modern disc brakes. This ultra-stiff, flex-free, lightweight, supreme performing is a true all-rounder and is not restricted to the ideal racing conditions that most other wheels in this class are restricted to. Cognition The ultimate in Zipp hub technology. Every time a conventional hub set starts to coast, friction within the freehub ratchet mechanism works like a drum brake to slow the rider down. The drag between hub shell and driver body during coasting is considered as efficiency loss, especially for road wheels. High drag also can significantly contribute to chain-dropping issues. The drag torque drives the cassette clockwise so the chain gets loose on the load side. The solution? The rear Cognition hub with AxialClutch technology reduces drag by disengaging the ratchet mechanism when coasting. It then uses magnets to re-engage once the rider starts pedalling. SawTooth The name given to the Zipp NSW variable depth 77/82mm rim profile. This design is the result of rigorous wind tunnel and real-world testing. The rim shape takes natures elegant design solutions and combines their precise engineering finesse to deliver a wheel that performs like nothing else before. Hyperfoil This technological design refers to the individual nodes that are part of the Sawtooth rim design. Each of these structures feature the Hexfin ABLC dimples that stabilise handling in gusting and strong wind conditions by increasing wind vortex shedding. The dimples create a secondary vortex around the outer rim surface, which in turn heightens the wheel control and saves rider energy from being wasted. Hexfin Aerodynamic Boundary Layer Control (ABLC). The Sawtooth dimple design consists of 12 nodes that are specifically clocked to start aerodynamic shearing at a rate of 50hz at a rider speed of 20mph. Sawtooth accomplishes this by inducing small sheet vortices that shed at a low magnitude, but at a higher natural frequency, thus decreasing the laminar bubble effect on the aerodynamically shielded side of the rim's profile to further reduce high yaw drag and improve crosswind stability.
