Bikes a sugar4,everytime you pedal the chain falls from the middle ring onto the granny ring,i have taken the front mech off,still does it,changed the crankset,bb still the same,could something else cause the problem,im stuck what to try next as only just got the bike off the bay,happy with it apart from this gear problem!
any ideas would be great,cheers gary

Front mech out of adjustment? Bent teeth on the chainring?

Is the BB to long? Did you replace the BB with one with the same size axle?

Try bringing the cset closer to the frame Sometimes a shorter bb helps. Middle ring ok on both csets you've tried?
