h1 id="sram-red-xg-1290-e1-12-speed-cassette">SRAM RED XG 1290 E1 12-Speed Cassette
Color: Rainbow
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.
