Zipp optimized its Firecrest technology to build a highly aerodynamic 82mm rim—the 808 Firecrest Tubular Disc Brake. Designed for efficient power transfer and stable control in time trial and triathlon competition, the 808's wide 27.5mm rim shape provides confident tracking in crosswinds and over rough surfaces. Built with Zipp's excellent 77/177 hubset that features optimized flange geometry and Sapim CX-Sprint spokes to increase lateral stiffness, this 1,1885-gram wheelset combines toughness and reliability in a wind-shedding package that has to be ridden to fully appreciate. Each wheel includes specially-designed Tangente Platinum Pro Evo brake pads, Zipp Integrated Valve Extender with valve-core wrench, rim tape, and quick release.
