This page is provided for reference to historical product information.

Fast, light and podium proven, the Zipp 303 Firecrest Carbon Clincher rear wheel delivers phenomenal aerodynamic performance, and excellent strength and handling along with clincher convenience.

  • Ultralight carbon rim uses Firecrest® shaping to optimize the aerodynamic profile of both the front and back halves of the wheel
  • This rim shape also offers incredible crosswind stability, performing closer to a box-section rim despite the 45mm deep profile; dimpled surface dramatically reduces drag
  • The wider rim profile increases side-to-side stiffness for responsive sprinting and cornering; also offers great control, comfort, and strength
  • Zipp 188 hub uses Swiss-made cartridge bearings with extremely smooth-rolling grade 10 steel balls; freehub shell is SRAM/Shimano compatible only
  • 24 spokes are laced radially on the drive-side and crossed on the non-drive-side onto the 188 hub
  • Contact seals in the hubs are effectively watertight when in place but can be removed to save roughly one watt of power come race day
  • Bearing preload adjustment can be done after clamping the quick-release skewer, so you can maximize your performance and enhance longevity
  • Oversize 17mm diameter axle delivers significant stiffness for minimal deflection and precise response to input; axle spacing is 130mm
  • The Zipp 303 Firecrest Carbon Clincher rear wheel has a maximum tire pressure of 125 psi
  • Please note: these wheels are clincher-compatible only and come with quick-release skewer, rim tape and Zipp Platinum Pro brake pads
  • Zipp's recommended maximum rider weight is 225 lbs. (102kg)

Made in USA.
