Shimano XT SL-M8100 1x12S right shifter

The ability to adapt anything to your needs is a pretty sought-after feature in any area, especially in cycling, where every slightest adjustment can lead to a change in performance, influencing the final result. Completing the new groupset, Shimano designed a shifter that will meet the needs of even the most demanding riders.

Specifically: the shifter (version M8100-IR) uses a single screw mounting ensuring a clean cockpit, while the new Ispec-EV system allows an adjustment of 14 mm on the lateral axis and 20 degrees on the angular rotation, otherwise, you can use the standard clamp mounting (version M8100-R). Finally, a small but no less significant addition is a the soft rubber gripper on the lever that offers greater comfort and safety when shifting, even in muddy and rainy conditions.

RapidFire Plus

Mountain bikers have used RapidFire Plus since 1985 and it's still a winning choice for a wide range of riders from XC racers to freeriders. RapidFire Plus is suited to quick shifting, giving riders the ability to downshift three gears in one stroke.

2Way-Release

The RapidFire Plus shifter release lever is commonly called a trigger because it is operated like a pistol, by pulling toward the grip. The release lever of RapidFire Plus shifters from Shimano Alivio to XTR can be operated in this same manner but adds the ability to activate a release shift by pushing with the thumb.

Instant Release

Instant Release shifting replaces the two-stage click and release shifting you are familiar with. Instant Release shifting releases cable as soon the lever is activated, resulting in the quickest possible gear changes. Whether it is an upshift with a top normal rear derailleur or a downshift with low normal rear derailleur a quicker shift is always a better shift.

Multi Release

Previous shifting systems shifted faster in one direction than the other. Choosing top normal or low normal always meant sacrificing shifting speed in one direction. Now with Multi Release you can release shift two gears in one stroke. The result - the fastest possible shifting in both directions regardless of rear derailleur choice.
