    • Zipp 858 NSW Carbon Clincher DB Front Wheel 2019

  • Zipp 858 NSW Carbon Clincher DB Front Wheel

    The Zipp 858 NSW Carbon Clincher Disc Brake wheel design is based on the performance enhancing benefits of the 454 NSW wheelset and its design is optimised to provide the highest-level of deep rim performance. Equipped with an air-drag slicing 77mm rim depth, which features the unique, ultra-high efficiency Sawtooth and Hexfin technologies. These exceptional technologies provide unmatchable stability and control, to the point where this wheel design is not restricted to the ideal racing conditions that every other Deep Section wheel needs to be wary of; the Zipp 858 NSW is a true all-rounder and performs to the highest reaches of road cycling performance available in the industry regardless of the riding conditions.

    Stable, Efficient, Aerodynamic and Flex-Free

    This entire wheel construction is achieved using only the best materials, precise construction techniques and wheel building technicians. The wheel provides exceptional stiffness and is flex-free; with the added braking performance of the Cognition Disc hub, this wheel is the most stable and efficient, aerodynamic, deep section race wheel that he market has ever seen.

    Technologies:

    • SawTooth: The name given to the Zipp NSW variable depth 53/58mm 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 stabilises 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.
