Looking for help at appraising the following bikes. The single bikes are sizes ~48cm and ~52cm. Both from around 1978, lots of campy components including der's. TA cranks, Phil Wood hubs. 3T bars and stems. The Tandem is a little newer, around 1985 or so. Same parts mix generally, campy der's, TA cranks and Phil Wood hubs. Everything is in pretty good shape but some stuff needs replacing as you can imagine. Take a look at the pictures below and let me know what you think. Thanks very much!
