Shimano's XTR SL-M9000 shifter is the beginning of the line for actuating all the advanced technology found in the cutting-edge XTR 11-speed derailleurs and gears, so of course, it has seen an equal amount of attention and engineering to make sure it's up to par. That is to say, at the forefront of off-road shifting performance. The internals have been improved for a lighter, crisper action that maintains an even tension across the gear range. Ball-bearing movements are smooth as silk, and vivid shift feedback provides a distinct and assured indicator of every gear change.
The carbon shift levers feature two-way release so shifting can be done in the traditional finger / thumb RapidFire combination or with just the thumb alone. Polymer-coated inner gear cables are the same found on the Dura Ace road groups for a 20% decrease in friction, and the mounts are I-Spec II compatible for a clean and slim footprint on the bar.
Average weight is 102 g. Sold individually as a right (rear) or left (front, compatible with triple and double setups) shifter.
