Here is my 1991 Witcomb which was recently handed down to me by my father. It still has the same 7-speed setup when it was built, so I just replaced the shifters with Microshift and a Deore LX NOS front derailleur (had campy record brake levers, 105 front mech, and 600 indexed shifters). Long term I'm thinking of going 8-speed in the back with 10-speed Campy brifters, but this will work for now. Oh, and I threw on my fav quill stem, the Nitto Dynamic II.
