Zipp 303 Firecrest Tubular Rear Wheel

. The 303 Firecrest Tubular is built with a the latest iteration of our 188 rear hub, the V9, along with new spoke lacing pattern for the rear wheel refinements that result in improved stiffness and durability The new hub was developed in cooperation of superstar sprinter Mark Cavendish of the Omega Pharma Quick Step Cycling Team and is in use by other top pro cyclists and triathletes including Pete Jacobs and Mirinda Carfrae Cavendish received early hub prototypes in January 2013 and logged 13,000 kilometers 8,078 miles on continually refined variants, including his stage victories at the Giro dItalia and the 2013 Tour de France. His feedback helped optimize the hubs flange geometry, stiffness and weight The new 188V9 hub has larger precision Swiss steel bearings for increased durability. Our new virtual 3 cross lacing on both sides of rear wheel improves stiffness, achieving 3 cross stiffness in a 2 cross pattern with a new spoke geometry. The 188V9 has 25 percent more torsional stiffness than a leading competitive hub. This measure of stiffness is crucial for the direct power transfer to the rear wheel for out of the saddle sprints and climbs. The new hub also is laterally side to side stiffer that its rival or predecessor Features Max recommended rider weight 250lbs Rim Used 285v4 Hub Used 188V9 Rim Depth 45mm Brake Track Width center 26 45mm Max Width 28 50mm Nominal tyre Bed Width 17 98mm Spoke Count 24 Spoke Length Non Drive 264mm Spoke Pattern Non Drive 2 cross Spoke Pattern Drive 2 cross Spoke Length Drive 262mm Track Adaptable No Dimpled Surface Yes Ceramic Bearing After market External Nipples yes Weight 735gThe 303 is a wheel you can never count out. In 2010, it became not only the first carbon wheel to win a major cobbled classic, it won the two biggest classics Paris Roubaix and the Tour of Flanders. The wheel is light, utterly dependable and aerodynamic. And its just gotten even better Our exploration of the 303s wider rim led to the Firecrest technology. And now that development has come full circle with the 303 Firecrest. The new wheel features Firecrests signature shaping designed to optimize both halves of the wheel, which creates a rim that is significantly faster and also much easier to handle in crosswinds At just 1,255 grams, the weight of the new 303 is virtually unchanged from its predecessor and remains one of the lightest carbon wheelsets anywhere. Its 45mm deep rim outperforms much deeper rims with a traditional V shaped cross section. And yet, because Firecrest technology allows us to manipulate the wheels center of pressure, the new 303 handles like a box section rim. Its ultra stable, and suitable for even the windiest days And because the 303s new 26 45mm wide brake track at center has been optimized for wider tyres, the ride quality is better than ever 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 88188 hubset, reshaping the hub body and pushing the non drive side flange and bearing out by 7.5mm 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 Buy Zipp Wheels from Chain Reaction Cycles, the World's Largest Online Bike Store.
