As arguably the most tactile part of Shimano s Deore XT M8100 groupset, the shifters play a vital part. The dimpled long sweep paddle, grooved release paddle and Optislick cable provide a 20% decrease in shift effort and create an enhanced interface between rider and controls. Adjust to the optimal position for any riding style or rider preference with clean cockpitEasy and accessible front shifting improves efficiency and controlRider tune-ableLightweight and compact design boosts enjoyment on and off the trailThe XT shifter paddles are now slightly longer and more textured, with dimples on the thumb lever used for up shifts and vertical ridges on the smaller downshift trigger intended to provide a more positive surface to reach for in wet conditions. Like the previous version, they feature multi-release shifting, which allows riders to downshift two gears with one push of the lever whilst an improved vivid indexing mechanism guarantees shift accuracy. The ball bearing construction and slick-polymer coated shift cable enable a smooth activation.
