I have a friend of a friend of a friend who is selling his bike for $50. My friend's friend says it's a nice bike, 'super light and super fast'. My friend says it looks like a decent bike, but is probably too small for me. He says it has Maillard hubs, Rigida rims and Sachs derailleurs. Does anyone know anything about this model? A google search didn't turn up much (in English, anyway). Thanks!
