Zipp

The sizzling speed of Zipp’s 404 Firecrests is usually witnessed from behind, in the pack, as the rider with these speedy hoops pulls away. With the aero advantage of Zipp's 58mm-deep, dimpled carbon Firecrest rims, the 404s are a favorite in the amateur racing ranks and also in the pro peloton. Their agile weight propels them up climbs and allows rapid acceleration out of corners. At 27mm-wide, the rims not only increase your aerodynamic edge, they also provide a supple ride quality and impressive cornering while minimizing rolling resistance. Plus, you'll love Zipp’s incredibly stiff hubs with oversize axles and smooth Swiss steel bearings. And, everything is pulled together with fine Sapim CX-Ray spokes to give you every advantage on the road.
