Serial Number Update: Legnano and Frejus 5-digit numbers in the early 1970’s. Were they a shared sequence?

A lot was changing at Emilio Bozzi S.p.A. along with many of the other traditional Italian brands in the early 1970’s as the Japanese invasion hit full stride in response to a burgeoning North American ‘bike boom’ that exceeded the production capacity of European manufacturers.  Along with Cinelli, Bottechia, Olmo and Bianchi, the top models from Legnano and Frejus had huge cache in the USA during these years.  Thomas Aveina in NYC, Gene Portuesi in Detroit, Frank Samuel ‘Bicycle’ Jones in Long Beach, California and Paul Kent of Bloor Cycle in Toronto were a few of the prominent shops that sold Legnano and Frejus road bikes.

In compiling this website I have come across some exceptions to the rule. One such exception has been a few Frejus bikes constructed with the unique Legnano seat lug that put the binder bolt below the top tube and ahead of the seat tube.  When I first came across one of these bikes I thought it must have originally been a Legnano and someone had decided to refinish it as a Frejus.  Then I came across a couple of Legnano bikes that were built with the Frejus style of seat lug that still had their original factory paint.

The other thing that was common to many of the Frejus and Legnano ‘exceptions’ in the early 70’s was the serial number stamped vertically on the left side of the seat tube just below the seat lug.  So what was going on?  One thing is certain, the practice did not last long at Legnano as all formats of serial numbers or production numbers were gone by the mid 70’s and the same seems to be true for the Frejus brand however I little more research is required on the latter.

The first two photos below the serial number 31114 is stamped on the left side of the seat tube on a 1971 Frejus Tour de France that I recently acquired.  The third and four images below show the serial number 31388 stamped in the identical location on a 1971-72 Legnano Olimpiade Record Specialissima (note that this Roma uses the Frejus seat lug).  And the last photos show the serial number 32141 on a 1972 Legnano Gran Premio in the same location and orientation on the seat tube.  All of these frames have their original factory paint.

The Frejus serial number registry on the Classic Rendezvous website lists numerous models from 1971-1974 with the same 5 digit serial number beginning with the number 3. In addition to the serial number listing on the site, the Legnano serial number registry on the CR website also shows the same 5 digit serial numbers starting with the number 3 for models produced during the early 70’s.

So what can we take away from all of this, if anything?  Were these 5 digit serial numbers beginning with the number 3 a common list to both the Legnano and Frejus brands?  And if they were not a common or shared sequence of numbers, how or why would they have two identical sequences of 5 digit serial numbers beginning with the number 3? Keep in mind that both brands were made in the same factory and the serial numbers were stamped into the frames before the bikes were painted.

However these five digit serial numbers, spanning from 31xxx to 35xxx only accounts for about 4,000 bikes which could not have represented the complete Legnano and Frejus production from 1971-1974 give the aforementioned ‘bike boom’ that was on at the time.  Perhaps these five digit serial numbers were specific to only a part of Bozzi S.p.A. distribution or for a specific export purpose?  A three of the examples above are bikes imported into the USA however a Legnano Gran Premio with the serial number 32072 is owned by Paul Page in the UK at the present time.

Coming full circle to where this post began, the image above is a Frejus from the very early 70’s, serial number 33173, that is owned by Eric Fagerholm as posted on the Frejus page of the Classic Rendezvous website. From the photo it appears that this frame has not been refinished and yet is sports the classic Legnano seat post lug rather than the traditional Frejus seat lug and the fork crown is also a type used on Legnano models in the early 70’s.

It is important to reinforce that this bit of ‘mix and max’ between the brands was only taking place in the early 70’s to the best of my knowledge. So fellow enthusiasts and collectors, no definitive conclusion to be reached here but some clarification and observations that may get us closer to an answer down the road.


Update: August 17, 2017

I just purchased a 1972 Frejus Champione del Monde from the original owner that is constructed of Reynolds 531 tubing, the original factory paint and as you can see it has the unique Legnano style seat post lug and binder bolt. Always wanted to have one of these in the collection.

  1. Just want to say a big thank you for all your hard work and time on the Legnano bicycles! I have been fortunate to have acquired two this year. The first a 1971, I believe, and the second a 1953. The first is what I am reaching out for this time. The serial number is 31186 and follows the format discussed in this section. I couldn’t figure out the odd seat tube lug and had never seen another Legnano with it until I read through your article. It in fact has the Frejus seat tube lug on it. I hope to be able to post pics of both, with details of both bikes. Both are original paint. Thanks again, Kevin.

    • Hello Kevin,
      My apologies for the delay as I have been travelling. The short answer is yes, I believe the the 5-digit numbers were shared by the Legnano Roma and Frejus Professional models in the early 70s given that they were being made in the same factory and where essentially the same frame/bike with the exception of the paint and decals. If you want to pass a long a few photos ( of your 1971 Legnano including an image of the serial number I may be able to be a little more specific.
      best regards,
