Re: Few dumb questions
you are not listening, haste. if you had shortened the chain too far, it would not allow the rear wheel to move. trust me, i have done this. the chain popped off for one of two reasons, chain is not aligned or does not have enough tension. if you can wiggle the chain only a little bit and it does not droop when you let it go, then you have enough tension. if this is not the case, you need the tensioner. if chain is tight enough, check the alignment. sometimes it could be both. so check both no matter what.
