Serial Number Dating

This Olmo Serial Number Dating site correlates serial numbered Olmos with original dated bike parts or provenance to establish Olmo dating by serial numbers. Started in 2015.... Peter Brueggeman

IT APPEARS THAT OLMO DID NOT FOLLOW A LINEAR ALPHANUMERIC OR NUMERIC SERIAL NUMBERING SCHEME THROUGHOUT ITS PRODUCTION HISTORY,... but bikes similarly numbered seem to be of the same time period.

Not all Olmos have serial numbers. Alphanumeric serial numbers were used before 1970. Numeric serial numbers were used from the late 1970s, and then discontinued. Lower level models may not 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 ? 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.

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. However a few Olmos with Brianza lugs have Rondine decals, so go figure. Olmo produced a Velital brand bicycle.

Dating bikes by bike parts is not an exact science since dated parts could be used into following year(s).

DECALS: Hans Mirsch: notes it has square outline of former decal on head tube, and a decal removed from seat tube. "I just received some more info from the seller, that he was told by the previous owner before him, that the fitted decals on the bike was ”Barale Bordighera” which seems to be a bicycle shop. This explains the strange measures on the old stickers. It was also fitted with a Reynolds 531 decal. According to the Olmo 1973 catalog, the Competition ”C” Titanio (is) available with either Columbus or Reynolds tubing. The frame takes a 27.0 seatpost, so it is Reynolds tubing. The seller also claim that it has not been repainted. I have now also checked the frame in detail and there is no preceding color (on steerer tube or inside bottom bracket or top of seat tube). One can easily also see that it has not been built up before."

Maurizio Coccia on 9 Dec 2016: "I also called to Olmo factory last Monday: I spoke with Mister Alessandro Baglietto; he works in Olmo since a lot of time. He confirm me: doesn't exist a register of their bike based on serial number and - today - they don't have a way to date precisely their old bikes. Code under bb, it's only a progressive number. Anyway: according to Baglietto that bike comes from 1982 or 1983, but he's not sure at 100%."

Eric Conrad: Olmo s.p.a. [all lower case] bottom bracket with a rectangular tented cutout; OLMO Type 1 head lugs; OLMO Type 2 seat lug/stays; OLMO Type B Fork Crown; star cutout in fork tangs; Olmo Type 3 rear brake bridge; round hourglass chainstay bridge with reinforcements; Olmo dropouts; chrome forks and chainstays with chrome ends; braze-ons for front derailleur, shifters, top tube brake cable, tire pump nipple on the head tube, and two water bottles; post-like cable guides under Olmo bottom bracket; Columbus tubing; this frame shares almost all its features with the Firenze #4502; Eric Conrad: "I believe this is the original paint. 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. ..."

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....
