With XTR M9050 Di2, front shifts require very little effort, with the swift tap of a button already at your fingertip. The digital control of Shimano's front derailleur means that the exact same input is used for each and every shift, the definition of reliability. Computer controlled auto trim means that you can remain focused on the trail ahead. The FD-M9050 is also Shimano Synchronized Shift compatible, so if you choose, a single shifter can control both front and rear shifting, custom tuned to your preferences.
