I've got a 73 Comp coming in the mail. It's just a frame/fork/headset and front and rear Huret derailleurs but everything else I didn't really want. It'll be a quasi Huret/Campy GS build as I have GS parts from the Gran Course I traded for it. I would of liked the Gran Course but it was nearly 10cm's too big. I'm excited but is there a write up on switching recessed nut style calipers on the GS calipers to something that'll work with the Comp?
