You may be searching for marginal gains, but there’s nothing marginal about Zipp’s 808 Firecrest tubulars. At 82mm-deep and 27mm-wide, the dimpled carbon rims offer an astonishing aerodynamic advantage. Not only do they slice the wind, they’re also some of the stiffest rims out there for explosive efforts and trustworthy power transfer. 20 front and 24 rear spokes are laced to equally stiff hubs — Zipp’s Track Hubs, which boast oversize axles for maximum lateral and torsional stiffness. Plus, Zipp’s Spoke Hole Impact Forming Technology results in even more stiffness, strength and flat-out speed.
