Sram cassette XG-1290 E1 12-speed 10-33T. rainbow

Wide gear range and narrow jumps? Why not both? Our lightest and most durable cassette also sets new standards when it comes to gear selection. Four different cassette options, including our first 10-30 and 10-36 RED cassettes, each offer secure shifting ramps designed specifically for electronic shifting. Whether you're racing with a 10-28 or building an all-road setup with a 10-36. Carefully selected tooth jumps guarantee that you stay in the right gear. For example, when you get out of the saddle on steep climbs or when you make finer gradations to stay on the rear wheel of the rider in front as you approach a sprint.
