Housing the same medal-winning technology as our other Transmission cassettes, our XS-1270 Cassette offers incredible performance with amazing value.

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.
