Hi,
My friends bikes chain keeps slipping to one side of the bottom jockey wheel and I can't work out why is is happening.
The mech hanger doesn't look bent so just don't know what it could be. It's a new rear mech too.
Any help would be much Appreciated.
Cheers Shaun
Chain line or hanger, at a guess.
Clear pics would help, but we'll need them from directly above and directly behind the bike.
Probably easier to roll it into a bike shop and get them to check it with hanger alignment a tool, it might not be visible if it's only out a little.
The mech hanger may be fine but is the mech straight.? I've had this many times before with new mechs.
Bent mech is my guess without pitchers.
Thanks guys. Was a bent mech. Was a lot worse than I thought.
Cheers
I'm always happy to be wrong if things turn out right 😀
