I managed to bend a brand new XT shadow rear mech which lasted one ride - in fact, it seized and twisted after less than half way through its first outing (20 miles in). I was using it with a 991 sram chain (also new) and a top end sram cassette. It could be that the chain length and the jockey wheel height adjuster are less tolerant than other mechs, not sure.
Whilst out on last nights local ride a few others were saying that had had similar issues with the XT Shadow... I tried to bend it back but it managed to chew up the new chain last night - so a new chain and XT shadow have been ordered and I'll be able to see them side by side just how much damage there is.
Anyone else have anything to share - I'm sure lots of you will have "I'm fine" messages.
I noticed that the star-bolt was loose and that the derailleur could be clunked from side to side. Is this normal?.
