Zipp 404 Firecrest Track Tubular

When racing on the track, small increases in efficiency can yield huge dividends. The 404 Firecrest Track Tubular is assembled with Zipp's stiff and aero 58mm-deep 404 rim and connects it to Zipp's 333 hubset with Sapim CX-Ray spokes. The 404 Firecrest rim strikes the ideal balance of rapid acceleration and aero efficiency to excel in any track event. At the heart of this 1,655-gram wheelset are the 333 track hubs. Designed from the ground up for the rigors of track racing, this impressively lightweight hubset makes use of oversized hub bearings and axles that work together to produce a wheelset with superior load-carrying capacity and bombproof reliability. The 333's hubshell also incorporates industry leading aerodynamics and asymmetrical hub flanges on the rear hub for balanced spoke tension, immediate acceleration, and flawless tracking through turns.
