I have a 30yeae old bike and I've never done anything special with the chain. Should I be worried?
I've never tried to find parts for a bike that old before, so that might be the challenge. I did have a late 70's Schwinn that I converted to a fixie and had no issues there, but that was a much more invasive job. At the end of the day, I'd replaced almost everything on that frame, so I had less compatibility concerns.
