The Shimano XT SL-M8100 shifter scores with low friction use

The Shimano XT SL-M8100 12-speed shifter (clamp version) is much easier to operate and is clearly more accessible than its predecessor. This increases focus and control while riding. The Shimano 2-Way Release Technology ensures delay-free pushing and pulling movements.

Rapidfire Plus
Rapidfire Plus has been used by mountain bikers since 1985. Rapidfire Plus is still the first choice for a wide range of rider groups, from Cross Country racers to freeriders and downhillers. Rapidfire Plus is suitable for fast shifting. The rider can shift down up to three gears with one shift stroke. All new Rapidfire Plus shifters, from XTR to Deore LX, are equipped with 2-Way Release. This means that the shift cable is released by pulling with the index finger or pressing with the thumb.

With 2-Way-Release, the shifter can be pressed and pulled to shift to the smaller sprocket or chainring. This allows you to adjust the shifting process to your personal preferences. All newer Rapidfire Plus shifters are equipped with the 2-Way Release.

Instant Release
With Instant Release, the spring and thus the cable are released immediately when the lever is actuated, which ensures an enormously fast shifting process. The delay caused by a two-step shifting process with click and release is eliminated, so that the gear change is considerably accelerated and improved.

Multi Release
With earlier shift systems, gear changes in one direction were faster than in the other. The choice of top-normal or low-normal always meant sacrificing shifting speed in one direction in favour of the other. With Multi Release, two gear changes can now be changed with one lever operation. The result: The fastest possible gear change in both directions, regardless of the type of rear derailleur used.

Excellent! shifts faster than the SLX, levers are also lighter, requiring less force and are more precise than SLX. I'd say there is palpable improvement even compared to the M8000 11 speed XT predecessor. can only recommend.
