Shimano XT SL-M8100 Shifter

To drive the precision shifting of Shimano's 12-speed XT M-8100 drivetrains, you need the proper rear shift lever. For both 1x and 2x drivetrains, that means the right/rear SL-M8100-R Shifter. This is the standard clamp-band version, please see the SL-M8100-IR Shifter for the I-Spec EV model. The RapidFire Plus shift lever delivers light and responsive rear shifting for improved control out on the trail. The design offers instantaneous push and pull movements in 2-Way release, as well as delivering Multi-Shift and Instant Release technology. No other shifter offers more. The M8100 engineering advancements enabled Shimano to reduce shifting operation force by 35%, and making main lever access quicker by 20% versus its M8000 predecessor. In other words, the improvements to XT M8100 go much deeper than adding a 12th cog.

The shifter features a combination of materials to achieve a durable, lightweight high performance mechanism. The main bracket is aluminum, as is the main lever body. The release lever body is a combination of Graphene Fiber Reinforced Plastic (GFRP) and steel. The base cover is also GFRP. The clamp bolt is stainless steel. Each material has been selected for the balance of function versus material performance. XT has a reputation as the most durable, cost effective component range in the mountain bike world, and this attention to engineering detail is why. The shifting mechanisms operate on a pair of sealed bearings, leading to smooth linear shift actions with absolute minimal friction. This mechanical system, with a complicated but long wearing gear drive enable the shift function, with the various use and release actions, including the 4-cog Multi-Shift capability of the main lever.

Shimano equips the SL-M8100-R Shifter with their top-end, pre-lubricated OT-SP41 outer housing, which carries the OptiSlick Coated stainless steel shift cable. This proven combination is ideal for the stress and requirements of the 12-speed rear drivetrain, especially on full-suspension bikes, where travel pivots greatly impact housing performance. The shifter also carries the derailleur cable tension adjustment knob you need to keep you system dialed in. At just 117 grams, the XT SL-M8100 Shifter is crucial to 12-speed drivetrain performance and it will deliver flawlessly, shift after shift as you power up and down trails that ask everything of you,
