Citoyen-Thank you for this information. I recently unearthed a very nice older Primato and faced some challenges id'ing the model year and tubing. Other than some helpful forumites, it took an email to DeRosa for further explanation. They, as well as another local owner of a similar Primato, reported that my wife's bike was part of a special order by a local shop. There were other interesting elements to this such as a copy of the original invoice that list these Primatos as a "Racing" model with no other special details. The paint was also a special order item. The closest I have seen to this model is the mid-90's Giro D'Italia. So, a little tricky to figure this out. I am taking pictures of the bike to Italy this summer to talk to folks who also may be helpful.
