Mystery Frame - Columbus Sl, Dura Ace

[Michum]

Hello, I need help to identify this frameset. I think that it is missing some decals. Thanks in advance

The lack of braze on front mech and internal cables put it late 70's early eighties. A frame number would help...

With that spec I'd guess mid-80's. Looks like a quality unit.

Looks nice enough, but pretty generic. Not a bad thing, mind you, but without further clues it will be nigh impossible to identify. I would not be surprised if it came from one of the larger shops in Italy or Belgium that built 'blank' frames for others to brand.

Mid-eighties would be my guesstimate as well.

I've got this photo from a seller so nothing special i guess. Anyway i'm looking for italian bike for my dad rn to take him with me on next eroica in Tuscany so i will keep looking

Looks like it was sold by a Swiss shop. It could be a Swiss frame, but I think Italian is more likely. A look at the underside of the bottom bracket shell may tell you more about the maker.

I think it is a nice bike, and the Dura-Ace 7700 stuff is really excellent. While it is borderline in terms of age, it would make a pretty good bike for L'Eroica, in my view anyway.

The biggest limitations will be the maximum tire width (not much room left under the brake bridge) and low gearing. The rear derailleur will probably handle no more than a 28-tooth cog and a 38-tooth inner ring is the smallest that will fit the 130 BCD cranks.

I know that it will make a great ride but my father just loves Italy, that's why i'm looking for italian brand bike. I've never tried this dura ace but 105 and 600 already works excellent and i wonder that dura ace would work crisp as hell. Eroica allows bikes made before 1987 but everything will be okay if it meets the cable guiding, 36h low profile wheels and downtube shifters.

Hmmm, maybe a Mairag?
