Help needed - Is this an 80's Guerciotti?

Does anybody have idea what is this bicycle frame? We are considering with a friend restoring it and would be grateful for any info, also is it worth it.

Frame is totally without any stickers or manufacturer marks, only spray on it. Only thing characteristic are stars visible on the two connections and under bottom and probably Campagnolo hooks.

Stars could indicate that it is probably old Guerciotti frame, but the shape of star is regular, not "streched" Guerciotti star. Also there aren't any marks on fork and monostay.

The Guerciotti's I've seen are pretty distinctively marked, and I think yours is something else. No idea what, although it looks like a high quality frame.

Guercs I've seen had neither the stars in the lugs, nor the spoon seat stay attachment. So I'm saying not.

I am thinking Guerciotti. Haha phone edit.. Stars in lug and seat stay were 80s for sure, although this could be older with no panto on seat stay or fork. Not sure of prior years. Also frame size stamp on bb near the star cutout is similar to Guerc. Does brake bridge have the ten speed drive logo stamped in it?

Other possibility I see is Viner, but looks very guerc.

Unfortunately there are not any stamps on brake bridge or fork. I doubt that there are any stamps under paint, previous owner probably sanded the frame and painted it with a spray. I some pictures of parts, i think some of them should be on the bike from the begining so maybe this will help guess year or manufacturer.

I would say that the "portacatena" holes in the DS dropout puts it in the 1978 to 1980 timeslot...give but not take.
And I'd lean toward "Viner" based on the shape of the stars.
But I'm not the expert on Viner nor Guerciotti..still, my 2 cents.

I think Unworthy1 is correct after looking at it on the computer, lots of similarities but the star shape and the fact they are at the seat tube as well but maybe @Henry III can ID, IIRC he has a Guerciotti in the age range of this bike and don't recall all the stars. Nice to see the portacatena, as mentioned in puts in a a pretty small window of years.

Viner has stars all over (scroll through pics).

85" Guerciotti, star is rounded.



No star at seat tube, stays appear similar

we don't know where the OP is located, but there are some oddities about how this bike is outfitted: the (apparently) Hatta Swan headset is something I've come to associate with bikes sold in Benelux, no idea why this would be but it seems that at least 90% of these Japanese HS were sold to Belgian or Dutch bike shops. Also the CTA bars are seldom seen on Italian frames, I wonder if these have FR (25mm clamp) dimensions cause the only ones I ever had did, but don't have any on-hand now to check. Anyhow, I'll bet this bike's in Europe.

Total invigilation Bike is in Poland, but i don't know since when and which parts were replaced. Handlebar clamp is actually 25 mm, not 25,4.

looks like a good quality Italian frame, whether a Viner or some other brand, is there any sign of "rifling" in the steerer butt (fork)? And is the seatpost 27.2?
Certainly could stand some better components (like losing the Biopace rings, for one) and if that stem has been over-tightened to clamp the FR 25mm bars I would definitely get that fixed before riding this: you might risk a stem cracking failure and that could be BAD. The quick/easy fix is to just shim the clamp area (with aluminum can material) to fill the gap but depends on what that stem was meant to work with (might be anything from 25.4 to 26.0).

Seatpost should be 27mm or even less, but im using plastic caliper and now i'm thinking is it actually 0.05mm acurate, i will look for more accurate. I did not see any rifling at the bottom of fork tube, should i take off the front wheel and look inside the tube or it would be visible without that? How can i check for which diameter this stem is?

Viner with frankenbike build/rebuild, is my best guess. Not a Guerciotti, I'd bet my pink Guerciotti.
Certainly worth a nice restoration.
Cheers, Eric

where to begin? I'd do this if it were mine: keep the shifters. the front brake and replace everything else with good quality/good value components, nothing wrong with middle-range Shimano stuff (like 105) which will get you back riding without breaking your bank and let you decide if you really LIKE this bike...and I think you will.

I've been out of the loop here for awhile but I'm putting my money on that's it's not a Guerciotti. The shape of the star is different and much smaller. The cable guides are nothing I've seen on any Guercs and just the fact there's no branding of the name or logo on anything...seat stay cap, brake bridge, fork crown. Have you checked to see what threading the BB is?
