I've recently had a new chain, cassette and chain set fitted (although I didn't do the chain set myself). Since then the chain has fallen off several times (and jammed between the small chain ring and the frame), each time on changing down to the small chain ring. After it fell off the first time I adjusted one of the front dérailleur limit screws so the dérailleur moves just far enough to the left so as not to rub on the chain when the chain is on the small chain ring and largest rear sprocket. So I can't limit the front dérailleur movement any more otherwise it will rub on the chain, and yet the chain has still fallen off several times since.
The first time this happened I was on a hill climb and changing up through the rear gears (although not to the smallest sprocket) whilst at the same time changing down to the small chain ring. I've subsequently been able to reproduce this several times by gently pedalling along the flat and changing down to the small chain ring while the chain on the smallest rear sprocket.
Any ideas anyone?
