Rearing to go.

Shimano's XT Di2 M8050 groupset brings the precision of electronic shifting to the masses while opening up more customization thanks to wirelessly programmable shifting modes and button functions accessible through Shimano's E-Tube Project application. The M8050-GS XT Di2 Rear Derailleur ensures crisp, reliable shifting thanks to powerful motors that respond instantly no matter the riding conditions. A low-profile Shadow Plus design keeps the derailleur out of harm's way on gnarly trails while giving you seamless, stable shifting even with the clutch engaged.

Compatible with Shimano Di2 electronic groupsets only.

Agh yes, the joy of DI2

I have been riding DI2 since it was first introduced. I tried SRAM EAGLE XX1 on my new Jones mtb, but sold that off in a hurry and replaced with XT Di2. It is so nice to have the perfect-ever-time shifting of Di2. Sure, the SRAM stuff worked like it should, but was clunky, noisy, and crude compared to Shimano Di2.
