SRAM XG-1290 12 Speed E1 Cassette

Great range and tight jumps? Why not both? SRAM's lightest, most durable cassette is also pioneering gear choices. Four different cassette options, including the first 10-30T and 10-36T RED cassettes, each offer safe shift ramps designed specifically for electronic shifting, whether you race on the road on a 10-28T or create an all-road setup with a 10-36T. Carefully chosen tooth jumps ensure you stay in the right gear when out of the saddle on steep hills and make fine changes to hold a wheel as you approach a sprint.

• Designed for smooth and fast shifting

• Gradual gear progression between sprockets - at least five jumps of one tooth on 10-28T, 10-30T and 10-33T cassettes - while still offering a longer range

• A 10-tooth start provides greater gear range

• 10-30T and 10-36T options available for the first time in RED

• Designed to work with an XDR driver body

• X-DOME one-piece machined steel design for weight savings
