I need help regarding identification of this frame
 

Hello.

I recently acquired a sleel frame road bike, and I had some problems with identification of the frame.

Paintjob is most definitely not original...
Bicycle runs on Shimano 105 1055/1056 components (Shifters, Derailleurs, Super SLR Brake Levers and Calipers).
Handlebars and stem were made by 3ttt, it is the 3ttt mod superleggero.
Seat is Colnago Master C40, carbon fibre seat with titanium rails.

Any information would be helpful.

Regards, gregor89.

It's Italian, in DeRosa's style - what is the cut-out on the head lug and seat lug? Heart?

DeRosa also built frames for other marques - I believe they built my Moser.

If it's a DeRosa Primato, there should be a heart pantograph on the rear brake bridge, but all the photos I've looked at, that's the only pantograph on that model.
My Moser frame is a virtual twin without the heart and a different brake bridge...

Are you sure that's a heart cutout? It's a window for sure, but I couldn't tell the shape.

Unfortunately lug cut-outs are more triangular-ish rather than heart-shaped

Rear brake bridge seems preety blank, altough there might be something under that paint...
Nothing that is visible unfortunately...

I didn't say it was a heart - I asked, but sure looks like a Primato frame - wouldn't surprise me if it was built for another marque.

The serial number is likely buried under that paint, and unless you have your heart set on repainting it, I wouldn't suggest sanding down to it.

That lug set was not uncommon. It bears similarities to my '76 Team Professional, but the seat stay treatment is very different, your frame has internal cable routing, and an extra stylistic element on the fork. I don't have anything to contradict bulldog's hunch, but I think the other information that might help establish the identity are the dropout manufacturer, the bottom bracket threading and the seatpost diameter.

agree, it's from the age when the dropouts might be branded for the frame marque.
The dropouts on my Moser are stamped Moser.

Italian? very likely.
DeRosa? very unlikely.
All I can say for sure is the headlugs and other (visible) framebits look fairly common and fairly generic, the brake bridge MIGHT be a GPM and the dropouts MIGHT be Shimano (Yes, Italians sometimes used them), but hard to ID with the pics displayed. Edit: on second look I think more likely GPM or some similar Italian brand forged DO, don't think they're Shimano now.
One thing that's distinctive is that forkcrown which is the same as on my early '90s Ciocc, which this frame is NOT...still have not ID'd what brand this Italian crown is, either but the forkblades were Columbus.
Also unless there are matching serial numbers that fork may not be OEM to the frame: the domed stay ends are not a style match to the forkend brazing, for example.

That's the first thing I noticed. The fork bade to dropout transition is quite nice while the stay to dropout transition is quite ordinary and unfinished.

There are 5 digits of the frame's serial number - 87652 (you can just about see the 8 on the photo from under the bottom bracket), but that is all I can see.

Whether the fork's serial number will match, I don't know, and since I had some big problems with loose steerer tube bearings I do not want to take it apart unless I really have to
(Bike came with steerer tube bearings that look like that lower one)

Dropouts have been painted over any information they might contain.

Bottom bracket thread is I believe Italian type.

Seatpost - Shimano Dura-Ace Φ 26.8mm

26.8 seat post may indicate Columbus Aelle tubing (for the frame, anyway, fork might be something else)...even if you don't want to remove the fork you can peer up the bottom of the steerer and see if the inner base has any "rifling": 5 shallow spiral ridges, sort of faint so you'll need a good light.

Might this be something along those lines??

Frame looks the same (with exception of external brake cable)

...And there is '80s Cilo Stratos:

looks pretty perfect

DeRosa was a relatively small production firm... There are stories about Ugo helping Eddy Merckx get his bicycle business off the ground, but I was not aware that they produced frames that were then sold under other brand names. Moser had DeRosa build HIM frames - to race on, but for retail sales?

I'm open to being schooled. Cheers, Eric

As others have said, the fork crown reminds them of a '90's Ciocc or a Cilo. For me, it reminded me of a '90 Rossin Prestige:

I must say they the Cilo example looks pretty close.

the Cilo Stratos linked to above has the most detail matches: same forkcrown; apparently same headlugs and fastback seat cluster, can't tell about the dropouts of forkends. Only thing I'd say is a 26.8 seatpost might be correct for Aelle but AFAIK Cromor tubing used 27.2 (can anybody confirm?) so might be a model just below the Stratos, or slightly earlier (assuming Cromor came along later to fill the Aelle tubing slot). But Cilo looks like a promising brand match.
