This shifter is specifically designed for fast-paced MTB rides as it offers light and responsive shifting for all riding styles. It features a 2-way release function which allows for relief shifts by either the pull of the index finger or the push of the thumb. One final highlight is Shimano's I-SPEC B mounting system which creates a cleaner and lighter bar set up.

Please Note: This Shifter is designed for use along with I-spec compatible brake levers only and does not come with its own round handlebar clamp. I-spec compatible brakes are required to be able to mount this shifter to your handlebars.
