Zipp 303 Firecrest
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 the revolutionary Firecrest® platform. And now the Firecrest revolution has come full circle..
Completely redesigned with Firecrest® shaping, the 303 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 Zipp's 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.
With the new Firecrest rim shape in Zipp 808 Tubulars and Carbon Clinchers, Zipp wheels make a bigger difference in more ways than ever. Not only is Firecrest more aerodynamic than any other rim design, it improves handling in crosswinds, wheel strength, and overall ride quality.
Every aspect of our 88 and 188 hubs sets a new benchmark. The standard steel bearings are the roundest in the industry. The 17mm axle is the stiffest of any road hub we've tested. When it comes to precision and performance, there's really no comparison.
Advanced Boundary Layer Control (ABLC) refers to the patented, dimpled pattern found on most of Zipp's rims. ABLC smoothes airflow across the rim's surface and is tailored to every model of Zipp wheel. Starting in 2009 Zipp implented the third-generation of ABLC, with up to 4 times more dimples than before.
