I welcome any feedback on this post and please enter your own Bianchi Proto. I am certain there are many versions/variants of Protos out there. I am under no circumstances believing or meaning my above post gives the full picture or is in all parts correct. It is a start. There are Proto, Caurus and whatever other Bianchi in MAX tubes out there that we still do not know about.
I will build mine as close to the one in the PDF file as possible – even if that one possibly is a year or so older than mine as it has the brake cable both entering and exiting on top of the TT. Mine entering under the TT. Yet a variation within the, by me known, Caurus: s (edit - I have since I wrote this post learnt that the one in the PDF has a higher serial number than mine - making it somewhat newer actually)
Regards
