bending aluminum frames
My mountain bike has a strange design for the seat stays and I am trying to put a larger sprocket on it but the chain is rubbing. So I was wondering if anyone has had success bending an aluminum frame, or are there any other methods out there? I think I may need to use a shim or two as well to move the sprocket towards the center of the wheel, but that only goes so far. I'm talking about 1/4 of an inch total that the chain needs to move.
