Bring SRAM Eagle Transmission performance to a traditional splined freehub with the SRAM XS-1270 T-Type Eagle Cassette. Designed for 12-speed T-Type mountain bike drivetrains, it combines a wide 10–52T gear range with smooth, precise shifting and dependable performance under load.

The 10-tooth smallest cog delivers useful high-speed gearing, while the 52-tooth climbing cog provides the low range needed for steep technical climbs, long trail rides and demanding e-MTB terrain. Full X-SYNC tooth profiling is engineered to improve both inward and outward shifting, helping the drivetrain change gears confidently even when pedalling hard.

Unlike other SRAM Transmission cassettes that require an XD driver body, the XS-1270 fits compatible traditional splined 8, 9 and 10-speed freehub bodies. The integrated 10-tooth cog and lockring make the full 10–52T range possible, providing a practical upgrade path for more wheels and bikes.

A 55mm chainline helps moderate the chain angle for improved shifting precision and longer drivetrain wear. The cassette also features a replaceable cluster for gears 8 through 12, allowing the most heavily loaded section to be serviced without replacing the entire cassette.

Finished in durable black nickel chrome, the XS-1270 delivers quiet running, long-lasting performance and excellent value for trail, enduro and electric mountain bikes equipped with a compatible SRAM T-Type drivetrain.
