Typical Shimano Quality

It took me awhile to get this to work properly. After a few attempts I went to the shop manual and followed directions exactly, and the derailleur works great. It's taking me awhile to make the shift to installing Di2, compared to cable actuated drivetrains, but once it was setup properly, it's great! Fast, quiet and I love the effortless shifting. B screw adjustment is critical, take note.

Super good for cyclocross

I have been using this derailleur in a 1x setup for cyclocross for the past month. It shifts perfectly and is super quiet with the clutch engaged.
