I need some help folks. I just nearly hurled my tandem into a ditch, and then had to push the stupid thing home again. Why? Because the chain came off. Am so angry because chains are a piece of p*ss to sort normally..not something that bothers me. But this one.. It came off in the middle chainring - the double one which connects front and back chains. So should have been a case of just whipping it back on. But the inner ring is so close to the frame that there is no room for the chain to pass unless its on the ring, which of course it's not. Everytime I tried to wind it round it just got jammed between chainring and frame. I tried it every which way and I cannot get it on. What am I missing folks? Is this a common thing with tandem chainrings, or just with mine? At the moment the only way I can see to fix it is to split the chain and thread it through that way, but I've never done that in my life so am a bit scared. Do have a chain thingy tool though.. Hopefully, I'm just being thick and someone can point out the obvious to me. Thanks people..
