SRAM XG-1290 E1 12 Speed Cassette Silver

Every part of RED has been refined to create an effortless ride. Light brake feel and comfortable ergonomics, smooth front shifting, fully wireless connectivity, and expanded gearing choices fit every rider and their needs. 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 the rider 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.Features•Designed for smooth and fast shifting•Gradual gear progression between cogs - at least five one-tooth jumps on 10-28T, 10 30T and 10-33T cassettes - while still offering a wider range•10-tooth start helps provide a wider geari
