OK, this is kind of an odd one
I cannot shift into the small chainring on my mountain bike. The front derailluer is XT and haven't had any problems with it in the past. When I try to shift into the small ring, the derailluer doesn't move over enough. I thought it was an issue with the limit screws, but when I had it in the stand I noticed that the derailluer itself is hitting the seat tube.
Basically, if I'm in the middle chainring and I shift into the smaller one, the derailluer moves, but is stopped by the seat tube before it can move over enough to shift the chain.
Any help is appreciated.
