Shimano XTR M9070 Di2 2x11 MTB Front DerailleurLong regarded as the most notable feature of Shimano Di2 shifting, the front derailleur performance remains the best in the industry, now with the additional capabilities of Shimano Synchronized Shift.With XTR M9070 Di2, front shifts require the same light effort of a rear Di2 shift, reducing effort and freeing up the rider to focus on the trail. The FD-M9070 uses computer controlled auto trim as the chain moves up and down the cassette to keep the drivetrain running smoothly. Shimano Synchronized Shift compatibility allows a single shifter to control both front and rear shifting.
