Shimano XT M8100 Cassette 10-51T 12S - Black/Silver

Deore XT goes 12 speed!
In 2019, the best-selling groupset of the Japanese component manufacturer, Deore XT, follows the example of SHIMANO’s XTR group that was already equipped with 12 sprockets back in 2018.
As a high-end groupset for everyone, the XT is becoming increasingly popular.
With the Deore XT CS-M8100 12-speed cassette, SHIMANO offers a cassette with a balanced gear ratio - just like the XTR.
It impresses with sprocket sizes of 10 to 51 teeth, resulting in a 510% gear ratio.
This huge gear range is especially appreciated by enduro pilots, since it allows them to master steep climbs and fast sections at high speeds and adjusted pedal frequency.
Those who prefer particularly small gear steps for XC and Marathon can go for the lighter 10-45 version.
Here, the gaps between the gears are still small for smooth shifting.
This keeps rhythm and pedalling frequency at a constant level for maximum propulsion with less effort.
Optimised shifting speed without chain slap caused by larger gear steps is another advantage of the Hyperglide+ cassette at XT level.
To get more space for the twelfth sprocket, SHIMANO has developed the Micro Spline freehub body that replaces the previous HG freehub.
