Remove front derailleur without breaking chain I recently purchased a Diadora Orbita bike from SportChek. As I was riding it my front derailleur got bent and now I can't use my pedals. So, my question is, can I remove the Shimano FD-TY18 front derailleur without unlinking the chain? I don't have a chain breaker, so my only option seems to be to remove the derailleur without unlinking the chain. Is it possible?
The pictures I've found of the FD-TY18 look like the pin across the rear of the cage is riveted in place. So, you probably can't remove it without a bit of work – through if the derailleur is damaged beyond repair it probably won't be too hard to either pry it apart (try holding with a screwdriver and twisting one side with pliers) or to cut it (and do double check that there isn't a screw there).

But before you do all of that, check your chain carefully. Many chains these days are connected with a master link which makes it easy to split the chain without special tools.
