Help with My Rear Derailleur, Please
I'm attempting to fix my cousin's bike, the problem:
The rear derailleur is moves out of position when the bike goes to change gears, and the chain is slipping constantly. The problem I can see is the smaller of the two cogs is broken slightly, but I don't believe that to be just the problem. Part of the derailleur goes from being parallel to the tier, to crooked.
The 1328 picture is what the derailleur looks like after the chain slips (obviously).
The 1332 is what the derailleur looks like when the chain is on.
If you need more pictures (which you probably will), just say so.
Any help would be greatly appreciated.
