Wide range and tight jumps? Why not both? Our 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.
