Shimano Deore XT CS M8000 11 Speed Cassette 11 40T Parts Mountain Cassettes

Shimano Deore XT CS M8000 11 Speed Cassette 11 40T. If you're running a dedicated single ring, 1x11 speed set up, you need a cassette with a huge gear range to make it versatile enough for trail and XC riding. The Shimano Deore XT CS M8000 11 speed cassette now provides an enormous 40T large cog, which provides an easier gear for those monster ascents. But Shimano didn't just slap a gigantic cog on the back of a 10 speed cassette. They carefully selected the cogs with their new Rhythm Step progression to ensure that the shifting feels balanced, smooth, and progressive, without any big or jarring jumps in the cassette. Plus, thanks to a cantilevered 11th cog, the M8000 cassette will fit on your 8910 speed freehub bodies for maximum versatility.
