SRAM Cassette XG-1290 E1 12 Speed
The SRAM Cassette XG-1290 E1 12 Speed is a premium SRAM cassette built for road, gravel and mountain bike riders upgrading their drivetrain. Engineered for smooth shifting, wider gear range and lower drivetrain weight, it brings the dependability and performance modern riders demand from their kit.
Overview
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.
