    • Zipp 454 NSW Carbon Clincher Front Wheel 2019

  • Zipp 454 NSW Carbon Clincher Front Wheel

    The Zipp 454 NSW Carbon Clincher  Front Wheel offers cyclists the greatest aerodynamic balance, cross-wind  stability and the exceptional drag-reducing performance of SawTooth and Hexfin  technology, combined with the legendary rim brake performance of Showstopper  technology.

    Speed, Control and Consistency

    Zipp engineers studied what made  things move fast in nature and what caused their efficiency to be so successful  and how nature solved similar problems such as speed, control, consistency.  Zipp took inspiration from the humpback whales fast and smooth movements thanks  to the special features on the leading edge of its pectoral fins and the unique  micro-texture of a shark’s skin surface, which gives it the ability to glide  effortlessly through the water; experiencing minimal drag. These features are  the key to the success of the 454 NSW wheels, only Zipp has fine-tuned the rim  surface to provide this exceptional level of efficiency as an aerodynamic  property opposed to natures effectiveness underwater.

    Features:

    • 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.
    • Showstopper: Showstopper is a complimenting pairing of a directional, moulded-in, texture with silicon carbide particles suspended in the surface resin.  The current media blast process applied to all Zipp rims increases the surface roughness of the brake track providing the rider with consistent and responsive braking. In order to improve this for the wettest of rides, Zipp have introduced a moulded-in groove specifically tuned for the Zipp Tangente Platinum Pro EVO Brake Pad. The grooves have been optimized to interact with leading edge (relative to the rotation of the wheel) of the brake pad and the four cooling channels. The leading edge of the pad and first two channels efficiently wipe water and debris outward, cleaning and drying the braking surface, while the second two cooling channels have maximum interference with the grooves allowing greater braking force than a smooth rim. The cleaning effects of the groove and pad interaction improve brake feel and consistency even in dry conditions.
    • ImPress: Zipp’s ImPress graphics technology prints graphics directly on the wheel, which allows the dimples to do what they were designed to achieve, to control vortex shedding and the rate at which air sheds off the wheel. Managing this is crucial to stability. ImPress graphics also give NSW a distinctive stealthy look.
    • 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.
    • 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.
