Wide range and tight jumps? Why not both? Our lightest and strongest cassette opens new roads even for shifting choices. Four distinct cassette options, including our first RED 10-30T and 10-36T cassettes, each provides secure shifting ramps specifically designed for electronic shifting, whether racing on the road with a 10-28T or creating an all-road setup with a 10-36T. Carefully chosen tooth jumps keep you in the right gear when out of the saddle on steep climbs and make small changes to hold a wheel as you approach a sprint.
