The 808 Firecrest Tubeless Disc-wheels are all about science to achieve speed. That’s the perfect approach for Zipp’s stiff deep-rim choice for criteriums, road racing, or any kind of hammer-fest. At 80mm deep, its rim is designed to make you faster in every way. Zipp’s Total System Efficiency design approach, or TSE, infuses the 808 Firecrest with new features, including a huge drop in weight from its previous iteration, well more than 280 grams. Also, the wheel is designed with a hookless and tubeless rim profile and 23mm internal width. That’s ideal for running wider tires at lower pressure for reduced rolling resistance and greater cornering grip. TSE attacks the four primary barriers to speed: Wind Resistance, Gravity, Rolling Resistance, and Vibration Losses. Full Carbon Firecrest.

303 S Tubeless wheels provide today cyclists the versatility they demand with the speed they crave. A key innovation in the 303 S Series is the ideal-for-every-terrain rim design, featuring a 45mm rim depth and a 27mm width, designed to optimize tire profiles at lower tire pressures. That helps to reduce rolling resistance and provides a more compliant ride. The 303 S borrows design concepts from the higher-level 303 Firecrest Tubeless wheels to gain speed through increased efficiency, achieved by creating a wheel with reduced wind resistance, rolling resistance, rider fatigue, and weight.UD Carbon Hookless Rim, Compatible with Tubeless tires only. Smooth Matte Finish. 176D Hub. 45mm Rim Depth. Item Specifications: Cassette Body Type, XDR, Defined Color, Black, Hub/Brake.
