Description
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 our 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.
