I bought this derailleur to replace one that I wore out. With the medium cage and proper derailleur
hanger, I am able to use an 11-42 cassette for my old legs. It shifts perfectly with room to probably use
an 11-46 cassette if it comes to that. I will never go back to mechanical shifting again.
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.
Love having clutch on my gravel bike, shifting is smooth as you would expect from Di2 components.
On my rig clears XT m8000 11-42 cassette without roadlink or similar extenders.
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.
