At just 1,805 grams, Zipp's 808 Firecrest Track Tubular wheelset is tuned for speed with an 82mm Firecrest rim shape for superior aerodynamics, stiffness and stability. Designed from the ground up for the rigors of track racing, the 808 Track uses Zipp's lightweight 333 hubset, laced with Sapim CX-Ray spokes for stiffness that satisfies even the strongest track racers. Confident lane stability and immediate acceleration comes from oversized hub bearings and axles, and aerodynamics are further increased by asymmetrical rear hub flanges and the proven air-smoothing characteristics of Zipp's dimpled rim technology.
