Shimano Deore Xt Cs M8000 11 Speed Cassette 11 42

Shimano Deore XT CS M8000 11 Speed Cassette 11 42. If you're running a dedicated single ring set up, you need a cassette with a huge gear range to make it versatile enough for trail and XC riding. With the addition of an 11th cog, XT now gives you a wider gear range and smoother shifting progression. The XT M8000 cassette now goes up to an enormous 42T cog, which gives you a much easier gear for those big climbs. But Shimano didn't just stick a big 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 old 8910 speed freehub bodies, no wheel upgrades required.
