This is my 60/70 Bertin C37. The frame and fork are Reynolds 531 Double Butted tubing. The rear dropouts and fork ends are Campagnolo. When I acquired the frame and fork it had only a brazed on rear deraillure cable stop. It came with a Stronglight 93 crank and bottom bracket, and a Pivo stem. Unfortunately I had the frame and fork repainted and therefore lost the decals. I've had it for over ten years and I've never finished a ride on it without saying to myself, "what a beautiful riding bike".
