Description While XTR has always been the group for light race performance at the cost of durability, XT has always been the high-end group that will durably do just about everything XTR will do but a little heavier and cheaper. The Deore XT CS-M770 cassette is no exception with long-lasting chrome plated steel cogs precision designed with Hyperglide shift ramps for crisp, fast shifting. Another smart advancement is overshift pins on the back of the largest cog preventing the chain from becoming fully embedded in the spoke/hub/cassette juncture and causing serious wheel damage. On the 11-32 tooth version, a four arm alloy carrier holds the last 5 cogs together to save weight and increase stiffness. On the 11-34 tooth version, a five arm carrier holds the last 6 cogs together. Ideally used with a Shimano super narrow HG 9-speed chain.
11-32 (11, 12, 14, 16, 18, 21, 24, 28, 32; 261 grams) 11-34 (11, 13, 15, 17, 20, 23, 26, 30, 34; 297 grams) Reviews Ordered by Most Relevant First

Perfect for training or racing
Mt XT cassette has performed perfectly all winter through muddy training rides on my mountain bike. It's performing so well I've continued with it into the racing season. Perfect shift every time.
