SRAM RED XG-1290 E1 – Ultimate Precision, Lightweight Performance and Race-Ready Shifting

Experience the next generation of road cycling performance with the SRAM RED XG-1290 E1 12-Speed Cassette.Engineered for the latest SRAM RED AXS drivetrain, this premium cassette combines exceptional shifting precision, an ultra-lightweight construction and optimised gear progression to deliver outstanding efficiency in every riding situation.

Featuring SRAM's advanced X-DOME technology, the XG-1290 E1 cassette is precision-machined from a single piece of steel, providing an exceptional balance of strength, stiffness and low weight.

The innovative X-Range gearing concept starts with a 10-tooth sprocket, delivering a wider overall gear range while maintaining carefully selected steps between gears. This allows riders to maintain their ideal cadence during high-speed racing, demanding climbs and long endurance rides.

Available in four gearing configurations – 10–28T, 10–30T, 10–33T and 10–36T – the SRAM RED XG-1290 E1 offers the flexibility to match different riding styles, terrain and performance requirements.
