I have the opportunity to score a nearly pristine Peugeot Grand Sport from the 70's? or 80's I don't know I didn't get the serial number. Anyway its got simplex shifters mounted to the stem and also Simplex Derailleur in front and the back one has Peugeot writen on the back. The rims are steel but have a crosshatch pattern on the sides where the brakes contact. I can get it for $50.00 It looks really nice and I took it for a short ride and everything works and it shifts really nice. Its got a Pletscher rack on it and a nice REI handlebar bag. Is it worth it? Like I said its in great shape. What could I flip it for any idea? Oh yeah and there is a matching bike only its a really large frame and its black and is in just as nice of condition. Oh yeah what is Peugeot 103 tubing?
