Shimano Deore XT Di2 Upgrade Kit M8250 For Shimano 12 speed microspline cassettes (10-51) I used this derailleur for about 1000 miles. Shifts immaculately. One small cosmetic scratch on the body (NOT from a big impact) and a bit of scratching on the back of the cage where the chain runs past it. See images and video (I had to trim the video to get the right file size for ebay) Free shipping and if you have any issues with it, I'll take it back immediately.
