I do hate mismatch parts! I like to be period correct, but am not as worried about trying to make it exactly like it would have been. Though most of my bike were probably sold as frames anyway. Campagnolo is always good! However, I also don't mind a classic look for a new component. I recently purchased some Velo Orange rims for example. Very classic look, though I can run wider tires. But they will be laced to Record hubs (is there anything else??
