Girardengo project

Jeff N

'Lil Knee Scuffer
Hi group,
I’m working on a vintage Italian project, I believe that it is a Costante Girardengo that has been chromed back in the ‘70’s by its owner. The two badges are gone (head and seat tube badges), so I am searching to replace those. I would also like to find a good replacement decal, if anyone out there has a lead on badges etc I’d love to hear about them.
Thanks!

Thank you for your reply to my posting, and for the resource sites, I had not run across either of those website and I appreciate having those to consult now.

Having searched photos and documents on Girardengo machines, I am a little surprised that none of the bikes I have seen use the lugs like I have...I wonder now if I am incorrect in thinking my frame to be Girardengo? I would appreciate hearing your opinion if you are so inclined.

My reasons in thinking it be Girardengo are:
1) head tube and seat tube badge holes
2) rear fender threaded post underside of brake bridge

Many thanks,
Jeff

seat tube emblem something not frequently employed by manufacturers; however, have seen it a time or two on non-Girardengo marked machines

bridges threaded for mudguard attachment on Italian machines fairly common in this era. IIRC holes are threaded 5.0mm X .8. have some Olmo and Torpado frames in me racks from this era which have them as well.

some Italian road racing models of this time actually came supplied by the maker with mudguards. they were employed by racers for winter training rides.

suspect the bridges with threaded holes manufactured by Agrati but have no hard information on that at this time.

have no opinion as to whether or not your frame a Girardengo. most examples from the 1950's and 1960's are constructed with the Agrati "AM" pattern lug set. if you browse the machines illustrated at "the barn" you may discover some done with the "BRIANZA" pattern lug.

to nail down a frame I.D., when possible, one must look at the combination of all the available clues. materials such as frame ends, lugs, crowns and braze-ons were of course available to all. one does occasionally encounter a feature which is proprietary to a particular maker.

in the case of machines badged Girardengo would expect there have been several manufacturers through the years. new bicycles today being offered under this badge. offerings include mountain, juvenile, condorino and folders.

Thank you for sharing your knowledge, you have been most helpful.

I think I will carry on with my painting plans and continue researching who made the frame. Perhaps another Girardengo owner can tell me the head badge hole spacing, that might be another clue to the manufacturer.

All the best,
Jeff

emblems -

forgot to mention in message above...

checked half dozen online classified sites for head emblems - none offered

majority of Girardengo listings are for paper items; but then you already know this if you have explored a bit...

if you satisfy yourself that frame of this make you could file a search for the emblems with the auction sites - would save a good deal of fruitless checking

as am sure you know the head and seat emblems differ

On his blog, he posted a wonderful story about a 1960 Girardengo.

Here is a Girardengo badged condorino type machine which looks to hail from the mid-to-late 1960's. Posting because frame constructed with the Agrati "BRIANZA" lug set.

Here is a second Girardengo badged condorino which looks to come from near to 1970. Its frame is also constructed with the Agrati "BRIANZA" pattern lugset:
