    • Zipp 303 Carbon Clincher QR Rear Wheel 2019

  • Zipp 303 Carbon Clincher QR Rear Wheel

    The Zipp 303 Carbon Clincher QR Rear Wheel features top-level, podium-proven performance and is suitable for any riding style you can imagine. It is light enough to spend a day climbing to the highest peaks without you ever feeling weighed down, but stiff, reliable and stable enough to race your way to the bottom at full speed. This full carbon wheel features the unique Showstopper brake track surface, which provides exceptional stopping power and brake balance in even the wettest of weather conditions while not decreasing your brake pads wear-life.

    Aerodynamic Performance

    The 303 Firecrest wheel design is fine-tuned and optimised thanks to rigorous wind-tunnel testing to ensure that air drag does not affect stability or your power-output when aiming to increase your performance. The power-transfer is increased further thanks to the precise wheel building procedure that all Zipp wheels are subject to. Every Zipp wheel is laced and constructed by hand and tuned to the highest-levels of performance; many World Tour events have been won on Zipp wheels and customers receive the exact same quality as their Pro Race Teams.

    Technologies:

    • 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.
    • 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.
    • Firecrest: A unique to Zipp rim profile that provides more aerodynamic finesse than any other rim design. It also improves handling in crosswinds significantly and increases the ride quality enormously.
