Red E1 XG-1290 12-Speed Cassette

Experience the ultimate in gear flexibility with our latest cassette innovation. We've redefined the boundaries of gearing options by offering four distinct cassette choices, including our first 10-30T and 10-36T RED cassettes. Each cassette features precise shift ramps specifically designed for seamless electronic shifting, whether you're racing on a 10-28T or crafting an all-road setup with a 10-36T. Our carefully curated tooth jumps ensure that you're always in the right gear, whether you're out of the saddle on a steep climb or making fine adjustments to hold a wheel approaching a sprint.

Key features:
