A TIPO RONDINE decal may or may not appear on some older Olmo bikes, and refers to the Agrati AM lugs, with 'rondine' meaning 'swallow.' Some older Olmos have the ornate Agrati lugs which Emilio Bozzi sold as Brianza sportiva lugs; the accompanying Agrati rear dropouts are stamped with a scalloped back. Campagnolo crank arms have a date code starting in 1973, consisting of a diamond (1970's) or circle (1980's) with a number in the center denoting the last digit of the year of manufacture, and then in 1985-9 with square and number in the center: 11 = 1985, 21 = 1986, 31 = 1987, 41 = 1988, 51 = 1989 plus some other examples. after the year of an Olmo in this registry designates uncertainty about its year or range of years.
It was possible to tell just by looking at them that they were far superior to any other hub available at the time.
Very nice vintage Italian Fausto Coppi / Fiorelli frameset, dating from 1958 - 1959, with "full" Campagnolo Gran Sport groupset. Selling some of those at the moment so make sure to check my other listings (or flickr account) for some more eye candy.
I believe the frame is from 1958 / '59 and was almost completely original with regards to the components that it came with.
Please tell me the serial number of your Olmo road bike, the parts that are original to the bike, particularly dated parts (see below), and link/provide photographs, so I can add it to this registry.
This Olmo serial number registry records dated bike parts or provenance, to attempt correlating a serial number to a year or year range. Serial numbers are stamped on the seat lug on older bikes, or on the bottom bracket underside on later bikes (sometimes matched by a serial number on the fork steerer tube).
