Tonight when I walked my bike and got back on, the chain was all piled up behind the cranks. I managed to turn the cranks a few turns and it worked again. Then when I coasted....same thing...seemed like the rear derailer kept feeding chain forward when it shouldn't have.
I had noticed before that when I was walking the bike in/out of the garage, the cranks were turning....I thought that was odd, because my husband's trek doesnt do that.
Maybe i should've bought a trek.
