Shimano Xtr Di2 Double Front Derailleur M9070

Shimano XTR Di2 Double Front Derailleur M9070. This is the industry benchmark for electronic front derailleurs, ensuring you'll make front shifts with the same quick, light touch as a rear Di2 shift. In fact, shifting becomes practically effortless, freeing you to focus on the terrain ahead. A computer controlled auto trim keeps the drivetrain running smoothly as the chain moves up and down the cassette. 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.
