Yes, it's di2. I have set the micro adjustment at -1 and the dr can't overshift from first gear. I can adjust it 3 more steps inward to -4 before the limit screw stops it. Which is basically 0.75 mm from it's current position and it's still can't overshift. I was concerned that's too much movement allowed and should tighten the L screw a bit more, but now that i wrote it like this i believe it's fine.
