Chain Fell Off? Shift It Back On! - No matter how carefully you shift, occasionally the chain may fall off the chainring. It's best to avoid handling the chain because you'll end up with grease all over your hands. Instead, you may be able to shift the chain back on. This isn't possible if it falls off when you're climbing a hill, because you lose your momentum and have to stop. But, anytime you're riding where you can coast for a few seconds, you can almost always get the chain back on by gently pedaling and shifting the front derailleur to move the chain toward the ring. Pedal slowly and lightly and the ring will grab and engage the chain and you'll be riding again as before. Voila! Chain fixed! No greasy tattoos! (If the chain jams, stop and manually reinstall it.) When a chain comes off repeatedly, something's wrong. Have us take a look at the front derailleur adjustment.
