this is a classic steel frame made entirely of columbus sl or slx tubing ( the sticker is torn right after the L so i dont know if there was an x or not) as you can see it has 2 cut outs on the bottom bracket shell as well as a 57 the size and a 2 which i have not figured out yet other than that there is not a single number on this bike and some one pulled every sticker at some point. It came fully equiped with campagnolo super record everything the stem and handle bars are the only pieces that dont seem to fit they are sakae world custom. i have been told it is a Masi , cinelli, colnago even a nishiki pro i really just want to know what this thing is. it is super light and made of excellent tubing any help would be greatly appreciated please see the attachments for pictures of all the details. thank you all in advance for any help you might be able to offer.

I added a picture of the whole frame and of the wheel sticker it came with competition champion tubulars and there was a sticker on the wheel that said "record du monde" i dont know if this helps i will try and add a picture of this other sticker but i am having trouble uploading it.

oh and yes it is an italian threaded bb and steerer tube

Gipiemme dropouts is something you don't see every day

If I were to take a guess, I'd say that it is custom made/demo/show frame some place close to Italy (Italian threaded BB, right?) in the 70s (need a picture of the whole frame; does it have a FD mount?) It looks like a great frame. I suspect that the 57 is the frame size.

I severely doubt that it is a major bike manufacturer frame with those Columbus signed pieces (they'd have their own signatures there). Could be a Columbus show/demo frame for a new tubing introduction (any ridges on the headtube, btw?) and that might make sense of the use of the Gipiemme vs. Campy dropouts

I've seen frames with just the same features, it's often a contractor who uses the "generic" Columbus-engraved stuff when making a frame that closely matches a "big name brand". One brand that employed similar GPM fittings was Colnago, and the many off-shoots like Colnago "Sports" models, Saronni frames and those weird 'Nagos for Belgium. Some of the frames sold as Giordano used them, too...I associate it with a second-tier frame...but not always, and it has nothing to do with GPM dropouts actually being lesser quality than Campy: given how often the Campy 1010B DOs crack, the GPMs might be better!

any ideas? or have we settled on a small manufacturer somewhere near italy i am sure that some one on this great forum has seen one of these before... right? i hope so my local bike shop that has been around since the bike boom thinks its a Colnago but i am not so sure.
