Shimano Deore XT 12 Speed Shifter SL-M8100

Rapidfire Plus 12-speed right hand shifter with Instant, Multi and 2-Way release to exceed the demands of ever changing bicycle designs and riding styles.
Light to the touch but positive and crisp, Vivid indexing provides a constant amount of shift lever force across all 12 sprockets.
2-Way release: the upper lever still performs the same shift function, but it can now swing in either direction allowing it to be released by the thumb or index finger.
Multi Release allows multiple gear changes with one sweep, further adding to the speed of shift.
Multi-bearing design uses two ball bearing units to provide a low-friction and reliable shifting action.
One piece lower alloy thumb release lever with anti-slip increases durability and gives sharp precise shifts.
For use with 12-speed transmissions only.
