It was only a matter of time before Shimano added a cog to its XT level cassette. The XT Dyna Sys CS M771 Cassette utilizes the same Hyperglide tooth and ramp shapes that were so successful in the 9 speed version, to move your chain smoothly across all 10 gears. The XT Dyna Sys is fabricated from plated steel, which gives you a high performance cassette that doesn't cost a premium. The spiders between the cogs are alloy and the entire 10 gears are secured with an alloy lockring.
