Serial Number Registry

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.
Track/pista frames are not included in this registry.

Thank you... Peter       =>       peterbman@gmail.com

Not all Olmos have serial numbers.
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).

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. Olmo produced a Velital brand bicycle.

OLMO DATING


Dating bikes by bike parts is not an exact science since dated parts could be used into a following year(s). A ? after the year of an Olmo in this registry designates uncertainty about its year or range of years. Absence of a question mark means there is some certainty about a bike's year or a range of years, established by parts dating, provenance, etc., or by preceding or following dated bikes.

It’s a beautiful 3 stage. Base coat, top coat, and clear coat."
DECALS Type D; MADE IN ITALY decal on top of downtube; 'Guiseppe Olmo' signature on top tube
DATING: T-MAR/bikeforums.net, regarding Eric Conrad's frame #4446: "... Other factors that would indicate that your frame is not a Firenze is the absence of a pump peg and bosses for only one water bottle versus two... Unless the frame has had fittings added and has been repainted, it is no older than 1984 by virtue of the front derailleur hanger and dual bottle bosses. However, it appears to have the the correct painted spear points with pin striping on the chainstays, so I believe the frame is in its original state, minus some decals. I believe the pump peg was added for the 1985 model year. The really early Firenze only had one chainstay chromed but was quickly upgraded to having both chainstays plated. Consequently, I'd place this frame circa 1985/1986.... Olmo made three models in 1985 using the exact same frame: Professionista (Campagnolo Super Record), Firenze (Galli Criterium) & Competition Victory (Campagnolo Victory)... The Firenze made its debut for the 1985 model year. It's not in the 1984 catalogue and the 1985 advertisement states "Olmo introduces the bicycle that fears no competition". Had this been the 2nd year for this model, they would not have used "introduces"... Member Straightblock's bicycle is a confirmed Firenze and consequently is no earlier than a 1985 model. We also known that it is not one of the very early production models because both stays are chromed, unlike the frames in the advertisement. It also has a different head decal. The serial number is 56-4502. ... this is only 56 frames removed from yours. ... Now, manufacturers typically start building the new models around September, so it's quite possible that both yours and Straightblock's were built in late 1984, but there is no doubt in my mind that Straightblock has a 1985 model and that the probability of yours not being from the same model year is extremely small. ..."

1992 Olmo

Jonathan Davies: 57cm seat tube/56 cm top tube Columbus dropouts; Columbus SL tubing
ORIGINAL PARTS: Shimano 600 brakeset, derailleurs, shifters, SPD pedals, headset, hubs seatpost, crankset with 53/39 Chainrings; 8 cog freewheel; 3ttt stem and 3ttt Competizione handlebars; Turbo Special saddle; Mavic SUP Clincher rims
DECALS: Jonathan Davies "What I thought was the selling bike shop's decal which is on the down tube near the shifters and has completely faded is in fact the Italian association of bike and motorbike manufacturers?."
DATING: Seller stated it was 1989. Jonathan Davies "The components carry the 640_ markings such as the rear mech which is 6403. As far as I can find that was introduced with the gen 2 version of the 600/6400 series for 1992. I've found a copy of a Shimano catalogue from that year.... This set is also distinctive in having the 'tricolour' markings, pedals made by Shimano under licence from Look, and was the last before they adopted the Ultegra name.
