Some photos of a frame I am trying to identify -- looks to be 80's vintage. Chrome "lugs" are a unique design I have not seen before.



Any thoughts on what type of bike this might be would be appreciated!

seat cluster looks very much like a version used on some ALAN Carbonio frames, but the fork seems to be not original (steel?)
there was also a Japanese-made frame sold by Performance that has some similarities, but also several important differences. Like the stays and seat cluster. Not sure if the maker of those was ever discovered, but speculation was it was NOT SR/Litage because of too many differences. Same frames may have been badged as a "DuralAll" as well as Panasonic and possibly came with AL-alloy tubes as well as CF or blend of CF and Kevlar fibers

EDIT, that mystery Japanese frame may be made by Nakagawa, but this ebay ad shows it also has major differences to the OP's:

Great lug junction shots, full on complete big picture might be helpful as well and we need to see the whole thing, just because too.

Exxon Graftek? Rear brake bridge is a little different but could be different years.

interesting possibility, but have never seen one with that bolt-on style seat say attachment. Still haven't seen 'em all by any means!

I was looking for the ALAN frame guide that was extremely useful for ID-ing the variants/model years of ALAN frames, but it's disappeared from the link I had saved (anybody have a working link or a copy?):
"ALAN guide co-authored by Andrea Bonfanti, the magician known on these pages as corsaclassic : https://www.registrostoricocicli.com...an/alan_guida/

the very early ('70s) ALAN seat lug had bolt-on seat stays, but then they brought it back (maybe) in a much later version. this is certainly NOT a 1970s ALAN, but as merziac says: we need to see more details, a clear shot of the DOs would settle if this was an ALAN or something else, right quick.

Here is a photo of the complete bike. Components are Shimano Dura-Ace and Crane. If the tubes are carbon fiber, is it safe at this age or does it deteriorate? Or maybe these are aluminum tubes?

Close. It's a Graphite:

Thank you for that information. Turns out I was too late to purchase the bike, but it may not have been a rider anyway due to the structural issues with the frame. But an interesting history.

I remember seeing one or two "Graphite" track bikes at the Northbrook velodrome circa 1975. I remember staring at the bolt at the top of the seat stays and thinking screwed and glued.

wow! non-fixie for the win!
One of only 16 made before this early bonded CF frame shuffled off into history, but as the OP says this one could have serious damage (to the seat stay) that might kill both the deal and...

I hope the buyer knows what it is, and not just strips it of its - admittedly lovely - parts and trashes the frame.

It kills me that I missed this one. Not that I needed another bike but the rarity is a draw. Someone seems to have swooped in fast and got it, so perhaps they knew what they were looking at.
