Hello, I purchased a bike a while ago, but I decided to part it out. It was mainly equipped with Campy Nuovo Record parts, it has an italian BB and the frame was resprayed with rattle can paint. I managed to strip some of the paint off in order to identify the frame and I would like to ask your help in my quest.
This frame has some peculiar details like Pista geometry fork, horizontal dropouts, but also a RD hanger and cable stop bosses. It also has a Columbus decal and a Colnago decal on the headtube (i highly doubt it is genuine). The headtube also has some small holes which i think would be for mounting a badge.
Unfortunately the forum won't let me post pictures (haven't reached the minimum post number), so pictures are available in my gallery.

Interesting bike.
my first question would be what type of bottom bracket threading.
a chance by the lugs it is French.
the Columbus transfer is questionable at this point.
the diameter of the seatpost that was fitted may assist too to an extent.
the derailleur hangar could well have been added.
I like it.

So is frame lugged? Is there anything stamped on the dropouts?

you can upload pics to your gallery and we can see them.

when you say horizontal dropouts with a hanger do you mean like the first pic or the second?

repechage

In his gallery the frame has track ends with an added derailleur hangar.
fork and frame ends also suggest French but threading would point best.
Lugs reminiscent of the Constructeurs

Quite an odd one but with an Italian BB I would say it's gotta be Italian, and I bet somebody like juvela might recognize this lugset (Bozzi perhaps?) and BB shell, perhaps even the trackends and fork crown: Looks like both the RD hanger and the cable guides were added in which case the paint and decals are also non-original (and as the OP says probably no way a Colnago!)' Maybe these pix from the OP's gallery will help:








EDIT: Thanks to this pic courtesy of VeloBase: it clearly has some similarities to on Emelio Bozzi lugset, but differences too. I think pretty certain this came from Italy but I have no other guesses.

repechage

I skipped over the Italian bottom bracket.
intriguing frame, pretty sure the under the bracket guides are later add ons.

Thanks for te information so far!
The BB lugset also has some round holes at the part where ir joins the downtube and the seat tube (see BB bracket picture above), which seems a bit different from the lugset posted in the previous post, apart from that they seem identical.

repechage

Round windows are an easy mod to a bottom bracket spigot.
Fischer and others made a fork crown showing similar.
might look for plugged headbadge holes.

attractive frame

I think I mentioned in the first post, there are 2 headbadge holes, in a horizontal position

hello dbalu,

you have certainly found a most excellent puzzle here!

this piece sends mixed messages all over.

may be able to work out a couple points but have no guesses as to manufacturer.

Lugs -

this is an Agrati pattern as is the photo posted above of the "Emelio Bozzi" set

Bozzi was a reseller of cycle fittings and accessories who published print catalogues back in the day

the company was not a manufacturer of lugs

[conclusion of homily]

the nozzle cut of the frame's lug pattern is one Agrati terms their "SPORT"; while the feature cut is from a different Agrati pattern

this is something the firm did; creating a new pattern by combining the cuts of two existing ones

Agrati's "SPORT" pattern nr. 000.8050/E/U came up in a discussion thread on the forum two year back. it was employed to build a Lazzaretti badged cycle of ~1969 which was eventually determined to have been produced by none other than Galmozzi -

https://www.bikeforums.net/classic-v...bike-56cm.html

the "SPORT" lug pattern combines the feature cut of the "AM" pattern nr. 000.8040/U with the nozzle cut of the "ROMA" pattern nr. 000.8020/U

have only encountered one other cycle built with the pattern used to construct the subject frame. it is a Vittoria machine constructed by Fiorelli and dates from around 1960. saved these images of it from a CL advertisement, apologies they are poor.








[Agrati offered their seat lugs in three configurations: a) bare, no binder ears and no malaguti plugs, b) with binder ears and no malaguti plugs & c) with malaguti plugs and no binder ears]

one big question with the frame is what is original and what is an alteration

if one takes the dropouts and brake bridge to be original then it must be a training bike concept which could be set up in different configurations; as track machine generally lack provision for a rear caliper brake

we need a visit here from Detective Chief Inspector MauriceMoss - he is sure to sort matters in no time at all

PS - one simple check you could make is to measure the distance between the two head emblem fastener holes. please specify if the measurement is over the curve of the tube or a straight line one. have an early '60's Fiorelli frame in me racks; can check to see if it is similar.

The frame eventually got sold. The buyer, an italian guy (who also has a website studying frame manufacturers) stated that this frame is a Brambilla made by Pogliaghi.
