SRAM Red XG-1290 E1 12 Speed Cassette

SRAM Red XG-1290 E1 12 Speed Cassette

• 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 gearing range.

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

• Designed to work with an XDR driver body.

• One-piece machined steel X-DOME design for weight savings.

• Available in 10-28T, 10-30T, 10-33T and 10-36T as well as 2 finishes, Silver or Rainbow.

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 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.
