Rear derailleur:

With the new M8100 version of XT, Shimano has upgraded the group to 12 speed and surpassed most others in both design, function, and weight. Therefore, in the M8100 you get almost an XTR group for the XT price.

The rear derailleur is 12-speed up and fits all Shimano's 12-speed units.

Can yaw over 51 teeth on the cassette (can take down to 10 teeth on the smallest gear wheel).

With a long arm.

Large 13-tooth gear wheels with sealed bearings.

Shadow+.

The rear derailleur is for a transmission that fits with having 1 chainring on the crankset.

Shift lever:

Shimano XT M8100 Rapidfire Shift Lever for Rear Derailleur.

The trigger in the XT M8100 is on the right side and controls the rear derailleur.

It is mounted with a clamp around the handlebars, so you decide exactly where it should sit.

There is multi-release when you need to shift up and down, so you can change several gears in one push. To get into a heavier gear, the trigger can be pressed both forward and backward.

According to Shimano, 35% less effort must be used to shift and it has become 20% faster.

It is light and responsive, so you don't have to use extra energy on your shifts, so you can keep control and concentration on the track.

Cassette:

Shimano XT M8100 10-45t Cassette.

The 12 speed Shimano XT system is made for both the exerciser and the competition rider.

It mounts on a Microspline cassette case, so you can't mount it on a regular cassette case.

With the new system, it also runs with a 10-tooth cog as the heaviest gear, so the cassette spread is wider and that gives you a higher top speed.

Chain:

Shimano XT M8100 chain.

A new and improved chain has been designed for the XT M8100 12speed.

It uses the same technology from XTR, so it has extended inner plates that improve durability, increase the engagement of the teeth and it is better at keeping the chain in place.
