Shimano XT CS-M770 9 Speed Cassette

Smooth shifting and a lower weight thanks to the alloy carrier, the Shimano M770 XT cassette fits all Shimano compatible 8/9 speed cassette bodies. It features an aluminium lock ring, spider arm design and is compatible with 9 speed drivetrains. There's even pins behind the largest cog to help stop the chain from damaging your spokes.
