My di2 (6870) rear shifting has gone sloppy. There seems to be a bit of play in the knuckle of the RD - I can push it a few mm side to side. Seems worse in the small ring which I guess might be because of less chain tension.
Is my RD shot (it's probably 7 or 8 years old) or is this normal and I just need to adjust it?
