SRAM GX Eagle - XG-1275 - 12-Speed Cassette
The SRAM GX Eagle XG-1275 12-Speed Cassette delivers race-proven performance, crisp shifting, and exceptional durability for trail, enduro, and all-mountain riding. Available in both 10-50T and 10-52T options, the XG-1275 gives riders the flexibility to choose the gear range that best suits their riding style and terrain.
Both versions feature SRAM's lightweight XG construction, compatibility with XD™ driver bodies, and seamless integration with all SRAM Eagle 12-speed drivetrains.
The original 10-50T cassette was the first-generation Eagle design, offering a 500% gear range. The newer 10-52T version expands that to an impressive 520% gear range, providing an even lower climbing gear for tackling steep, technical ascents while retaining the same high-speed 10-tooth top gear.
