Shimano XTR Di2 Double Front Derailleur - M9070
The XTR Di2 front is Shimano Synchronized Shift compatible, which means you can use a single shifter to control both front and rear shifting. The derailleurs communicate gear position and automatically execute front and rear shifts when you ask for a sequentially larger or smaller gear. This improves your efficiency by minimizing time spent in smaller chainrings and cogs.
