Yesterday I called the shop in Rome that sold this bike originally and this was a custom order to Moser from a customer that wanted a TT bike with the geo of the Francesco's 1994 hour record bike.
The shop still has a picture of the bike when it was builded but unfortunately they don't have any internet connection to sent it to me.
The guy said they'll try to contact the original owner and ask him to forward to me technical informations and the pictures as well.
Apparently they used an Ambrosio lenticular wheel and they spaced it correctly.
I hope next week I'll have some good news.
