The M8100 12 speed shifter features everything that you know and love about Shimano shifters. Instant Release technology means immediate action at the derailleur and Multi Release technology means you can quickly drop up to 2 gears in one push of the lever. The 2-way release design means you can move to a harder gear by pushing or pulling the up shifter and with its ball bearing construction, less force is required to activate it (35% less than the M8000). The XT M8100 provides precise and effortless shifting all day long.
