It might save me on patches as I have many of both lying around the place, tubes and tyres that is. Also can anyone suggest some cranks that can handle abuse? I have ruined three sets, now on my DiamondBack, I have the good original right hand crank and a good left crank, this one came off a bike with a bockety right crank, this left one is about 1.5cm shorter than the right one , this is why I need three sets of cranks. I don't want to talk about my Raleigh, the wound is too fresh.
