Front Derailleur (3x)

The XTR Di2 M9050 Down Swing Front Derailleur features easy shifting at the press of a button, improved gear tracking and reliable gear changes even under load. It is meant to be used with a triple crankset. The FD-M9070 is used in 2x11 setups.

It also supports Shimano Synchronized Shift and computer controlled auto trim. Note that you need a display in order for synchronized shift to function with MTB derailleurs. I recommend either the SC-MT800 display, or its XTR equivalent, the SC-M9051.
