+1 about vintage European bikes, I was thinking about putting the Dérailleurs on my PX-10 the other day, All though a coaster brake nexus hub+mustache bars are dam temping as well, or maybe roller/drums brakes, and a dyno hub, a very utilitarian style bike, Sheldon maybe a dork, but you cant really argue with the logic behind his rides

And mark my words cheap Carbon Tubulars are gona be huge it begins wait for a cheap carbon version of that, And CF Everything, seatposts stems, all that, and Loads of CF on old European bikes,
