I'm currently building up a Rixe touring bike, from maybe the '70s or '80s. Info is so scarce that I'm lucky to get wheels that fit! Also, it was never a really high end bike--- apparently some of them were built by Raleigh, so that's the direction I'm going. Mostly, I'm adding components that fit as I find them. I've already violated OEM by putting in a sealed cartridge BB. My goal in a "restoration" is to make it better than new, eliminating known weaknesses as I go, if possible. Who keeps a bike stock, anyway?
