I have a 1976 or Gran Jubile' mixte that is sitting in the "wings" waiting for me to clean up. It has Campy Record hubs and Mavic wheels with first generation Cyclone FD/RD. Suntour power shifters. I am a long legged guy , so I haven't been too motivated to fool with it . It is a very nice bike though. I paid $120 for it years ago.
