Housing the same medal-winning technology as SRAM's other Transmission cassettes, their XS-1270 Cassette offers incredible performance with amazing value. Finished in a unique black nickel chrome, this cassette is quiet, durable, and features a replaceable cluster of gears 8-12. And for the first time on a traditional splined driver body, features a full 10-52t range thanks to the 55mm chainline and integration of the 10-tooth cog and lockring.
