SRAM Red CS-XG-1290-E1 12s cassette | 10-36T

Wide gear range and close gear spacing? Why not both? SRAM's lightest and most durable cassette also sets new standards in gear selection. Four different cassette options, including the first SRAM 10-30 and 10-36 RED cassettes, each offer smooth 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 ensure that you stay in the right gear. For example, when you stand up on steep climbs or when you make finer adjustments to stay on the rear wheel of the rider in front of you as you approach a sprint.

Manufacturer's note: Only suitable for use with Flattop® chains.
