I lost the ruddy key for years, but I know I also found it again, now not sure where it is again. I'll take some pics and look for keys, see what they are new and price accordingly at less than 1/2 to give you some idea. I don't have a tow bar on my bus or family camp, gave my bike to son has my bike so might as well sell. Not sure as I usually hung chairs on it and only small kids bikes the one time.
It only dropped an inch! But finger between sharp edge of flywheel teeth and a wooden block and it wouldn't stop bleeding however much masking tape I wrapped round it. Still hasn't despite the comedy bandage from A&E. Flywheel imprint on the next finget too. Got to go back tomorrow as well.
Ouch indeed!! You are right, it does look like one of the joke bandages - half a nail poking out of each side and you've got it nailed!!!
