Doe anyone have a geometry table for the older lugged steel frames? Like the Campione d'Italia or Mondiale or TSX? Did they change from one year to another? I am trying to find a late model (early 90's preferably) lugged steel frame. I typically ride a 55cm ETT so should I be looking for a 55 or 56 or 54 Bianchi? Did they measure C-t-C or C-t-T?? Thanks!!

From a 1996 booklet - RC frames 55cm size was 55cm c-t ST and 55cm c-c TT. Cd'I had 55cm c-t ST and 55.4 c-c TT.
B67, do you know what the HT length is on your Cd'I? I think I saw a 54 frame that had an 11cm HT length which is very short IMO. Thanks!

I have geo charts from 96 on but don't see head tube lengths listed. Just measured my 55cm TSX and the head tube is 114mm. Remember these bikes were built for quill stems and standard cupped headsets so the HTs are a lot shorter than modern frames.
