Zipp 303 Firecrest Carbon Clincher

  • Zipp 303 Firecrest Carbon Clincher wheelset

    Without Limits

    In the past two years, the 303 has emerged as one of the most formidable wheels in the pro peloton, with wins in the Tour de France, Paris-Roubaix, the Tour of Flanders and more. Its speed, light weight, and utter reliability have been proven in pro cycling’s most demanding races.

    In 2010, the 303 made history by becoming the first carbon wheelset to win cycling’s two most famous Cobbled Classics, Paris-Roubaix and the Tour of Flanders. Its wider rim provided extra durability, and improved aerodynamics. That wider rim also led to the development of our revolutionary Firecrest platform, and now the revolution has come full circle.

    The 303 has been completely redesigned with Firecrest shaping. The Carbon Clincher preserves the aerodynamic advantages of its tubular brother, while adding the convenience of a clincher tire. And at just 1,475 g, it’s light enough to climb up the steepest gradients with ease.

    All of the hallmark characteristics of the 303 have improved with the Firecrest Carbon Clincher. The Firecrest shaping optimizes the aerodynamic profile of both the front half and the back half of the wheel. In addition, Firecrest moves the center of pressure of the wheel backwards, giving the 45 mm-deep rim the crosswind stability a box-section rim. At the same time, the 26.4 mm-wide brake track (at center) allows the clincher tire to take on a wider, more stable shape without compromising rolling resistance. It’s faster, simpler, and more stable. Or as Zipp technical director Josh Poertner puts it, Firecrest is “lightning in a bottle.”

    The new wheels retain all the small details that make Zipp wheels what they are. Exposed spoke nipples sit in the aerodynamic shadow of the rims, keeping serviceability simple without compromising speed. And our signature ABLC rim dimples squeeze every last second of performance possible. To complete the package, Zipp has refined its venerable 88/188 hubset, reshaping the hub body and pushing the non-drive-side flange and bearing out by 7.5 mm on the rear hub to increase overall stiffness and strength. The wheelsets come with two decal options, the stealthy Beyond Black or the distinctive Classic White decals. Both decal options feature black anodized hubs, black spokes and black nipples.

    Note: Zipp wheels for model year 2013, which begin shipping in October 2012, are compatible with cassettes of up to 11-speed to work with all modern drivetrains.
