What is Shimano Di2?
Shimano’s Di2 (Digital Integrated Intelligence) is a shifting option to Shimano’s proven mechanical shifting.  Instead of mechanical cables, Di2 is an electronic gear-shifting system that enables riders to execute shifts with electronic switches vs. mechanical shift levers.  Through the use of Di2, shifts are fast and precise and customization options are endless.  The most important thing to remember as you read on, the user is always in control of what your system does or can be pre-programmed to do.

Shimano Deore XT Di2 FD-M8070 Front Derailleur (2 x 11 Speed) (Braze-On)
Powerful, versatile, and relatively easy to setup. I bought this for an ICE VTX racing trike, which I was converting to Di2 with the help of a friend who is a certified Cannondale bike tech. We were not able to get good shifting with an RD R8050 so we switched to the M8050 rear derailleur. Shimano no longer lets us mix Road and Mountain so we needed a Mountain FD. I purchased the M8070 which arrived in only two days. We set it up with an Ultegra Compact 50/34 crankset and had the FD shifting acceptably within an hour. But, it's a 32 pound trike, I'm 72, and we have some steep climbs. To give myself better climbing power I ordered a GX810 46/30 crankset. I swapped that out myself, and had it shifting excellently in 30-45 minutes. The sticker that you match up with the teeth on the chainring helps to set the height and angle. The shifts are quiet, powerful, and reliable.

One caveat, this FD is direct mount, and uses the Shimano proprietary bracket. It will not mount to a standard derailleur clamp. Not even with duct tape.
