The other day when I was riding my bike my fell popped off from the front gears and lodged itself between the bottom bracket and the smallest gear. In the process of dislodging the chain, I managed to twist a link in the chain about 20-30 degrees. Is this something I might be able to bend back with a pair of pliars or do I need a new chain? Or is it possible to just get that link replaced? Thanks for your help!
