Hey, all. I'm fixing up a Peugeot mixte for my girlfriend -- around 1980, I think; maybe a little older? -- and I definitely need to replace the freewheel and both derailleurs (possibly the chainrings as well). I want to keep it as a 10-speed, and I want to do it cheap (say, around $60 or less), but to end up with a good, reliable ride. I'd buy either new or used parts from any era. What would you recommend as the best freewheel and derailleurs for the job?
