    • Zipp 303 Carbon Clincher Road Wheels - XDR

  • Zipp 303 Carbon Clincher Road Wheels - XDR

    Packed to the brim with Zipp's innovative technologies, this 303 all-carbon wheelset is lightweight and responsive enough to suit riders of any skill level. A deep 45mm clincher rim offers excellent aerodynamics while also being stiff enough to make for a smooth riding experience. Additionally, the rim's 26.4mm width means better traction and power over rolling resistance, making this wheel more durable even on rough surfaces.

    Fully Optimised Hubset

    This wheelset comes with Zipp's 77/177 hubset, which has become a favourite of professionals for its ability to pair to with Sapim CX Sprint. The hubset optimises the spokes to offer remarkable torsional stiffness, making for a stable performance that maintains speed for longer.

    Technology:

    • 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.
    • 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.
    • 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.
