303 S Tubeless wheels provide todays 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.
