Shimano's game-changing Di2 technology uses powerful digitally-controlled servo motors, which are built into the derailleur bodies, to deliver clean and accurate shifting, time after time. All Di2 componentry is sealed and waterproof, ensuring performance even in the most brutal conditions. The Shimano XTR Di2 M9070 Front Derailleur improves upon Shimano's already widely-praised mechanical XTR front derailleur, delivering 20% more power to the shifting mechanism. The motor driven cage of the M9070 front derailleur pushes the chain across your chainrings with monstrous force that allows the chain to flow freely across the ramps and pins of your chainrings with ease. This power increase also results in no time lag when shifting under power, so when you're stuck on a tricky uphill you'll find no delays in finding the right gear. Shimano shortened the cage to accommodate big tires and the XTR M9070 front derailleur automatically trims right or left when it senses that the chain is nearing the outer edges of the cassettes cogs, virtually eliminating chain rub. Accessory mounts allow the Shimano XTR Di2 M9070 to be mounted in a variety of front derailleur configurations from direct mount to clamp-type. With the M9070 front derailleur, shifting has never been better and your mind never clearer as you ramble your way down the trail.
