SRAM Red AXS E1 Cassette

Wide range and tight jumps? Why not both? SRAM's lightest, most durable cassette breaks new ground for gearing choices as well. Four distinct cassette options, including their first 10-30T and 10-36T RED cassettes, each provide secure shift ramps specifically designed for electronic shifting, whether racing road on a 10-28T or creating an all-road setup with a 10-36T. Carefully chosen tooth jumps keep you in the right gear when you’re out of the saddle on steep climbs and making fine changes to hold a wheel while approaching a sprint.
