So I'm considering buying or trading for an old road frame (nothing specific yet, but something along the lines of Schwinn or Raleigh) as I'm really vying for a bit of a better frame (mine is hi-ten steel) and I know older road bikes from the around the 80s tend to have better tubing. I'm fully aware that I'd have to deal with conversion dropouts as opposed to track ends for at least some amount of time but there is an experienced framebuilder in my area who could swap the dropouts and braze on track ends for $100. This seems to me like a good idea on paper but I'm nearly certain that there's got to be more than a few problems with my plan, thoughts?
