Here I'd have to modify a derailleur to work with a 1/8" chain, route a cable, do some cold setting to center the wheel and set a chain line, decide on cogs and come up with some sort of roadsterish method of shifting. How about a TT mounted quadrant? It might be a better project than the light weight roadster project I never got around to.
Was the idea of the lightweight roadster to use a 531 or similar frame? That would probably have a derailleur hanger, at least, and probably a mounting point for a shift lever. I had no difficulty narrowing the rear triangle on the Peugeot mixte for the SA hub. Just used a carpentry clamp to squeeze it down little by little over a few weeks. I'm not sure the alignment is perfect but it wouldn't be hard to correct (if I was that much of a perfectionist, which at least with this bike, I'm not). The special antirotation washers for the wider axle slots would be nice to have but don't seem to be a necessity.
