I have an early '80s Raleigh Wyoming. I converted to 700c and cold set the frame for 130mm. I tried a 7 speed freewheel, but there's not quite enough clearance for it. I'm using the 6 speed version now, but I gather that I could try a 1mm spacer on the axle and it may give just enough room to get it to work. I thought I'd give it a try, but I asked a couple of bikes shops if they had spacers but they said no, and the only ones I can find on-line come in a bag of 20. Anyone have a source for one? Will I need to redish?
I had a similar issue, and the two LBS I tried didn't have spacers.... so I did the Amazon thing, figuring it can't hurt to have some extras in the toolbox for the future. IIRC, I needed 2mm for enough clearance for the chain to not rub the seat stay when on the small cog. The centering difference wasn't enough that I felt the wheel needed redishing, at least for now. I'll probably throw it on the truing stand and redish it over the winter.... if I remember.
