Hey all, I have an old 5sp freewheel on a shimano hub and I want to upgrade it to 6, ideally 7sp. The problem is that the axel is not long enough. I got the 6sp on and it fit okay, but the smallest cog rubbed against the frame. A re-dish wouldn't work 'cause there is not enough axel left.
So my question is, is it possible to swap out the axel. The rear spacing seems like it would work if I did.
