    • Zipp 454 NSW Carbon Clincher DB Rear Wheel 2019

  • Zipp 454 NSW Carbon Clincher DB Rear Wheel

    Taking nature and its constant adaptability as inspiration for this range of wheels, Zipp has studied the movements and behaviours of a variety of mammals, animals and sealife and applied their findings to this fast and efficient, disc brake-optimised rear roller.

    Nature-Inspired, Precision Engineered Rear Road Wheel

    Zipp has focused on what generates the graceful movements of the whale and the shark to create a rim profile that effortlessly cuts through the air. Combining the ethos of the leading edge of the whale's pectoral fin with the microtexture make-up of the shark's skin as they slice through water currents, they developed an undulating 53/58mm-deep rim, tried and tested in wind tunnels and the real world to achieve an unparalleled and unique performance.

    Reducing air-drag and side force at every wind yaw angle, this 454 model leaves its competitors in its wake as it pushes you on to glory, before reeling you back in with powerful disc brake compatibility.

    • Technologies:

      • 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 features 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.
