I just purchased a complete vintage aluminum Guerciotti bike, possibly from the '80's(?). Most components are Campy except the brake levers and pedals, which are obvious replacements. The bar and stem are Ambrosio, the seat San Marco. It is a six speed. The text "Made in Italy" "133931 3° 56x56" appears on the underside of the bottom bracket. The seat tube has the text "Tourist 569" stamped into the aluminum. In case you can't see the writing on the chainrings the text is "Brev. Campagnolo" also anyone can tell me which campy groupo this is?

Any help would be much apprieciated.

The group appears to be Triomph. The frame's made by ALAN.

+1 on gruppo and frame. 87 catalog shows very similar Alan frame which was called Sprint, available with either Suntour Sprint or Shimano 105

The pics are rather poor, but the rear derailleur cage looks like Victory, as opposed to Triomphe.

My first reaction was Victory, based on shape the cage and the jockey wheels being grey. But then I looked at one of my Campy catalog scans and saw the Triomphe came with with a similar cage and grey jockey wheels at one time. However the clincher for me on Triomphe was the retaining nut on the brakes. Victory (I have a set) are closed nuts, these are open and one of my Campy catalogs shows just this sort of nut used on Triomphe. But I have to say I would not mind seeing a close up of the crankset. The pic looks like it may have a self extractor, which would mean Victory. And who is to say it is not a mix of both?

I guessed Triomph based on the calipers... Triomph used the old rounder profile, and Victory used the tapered profile, like late Super Record. Both Triomph and Victory calipers used that simpler style of release, like the earlier Gran Sport calipers. Actually, most of those Guerciotti ALAN bikes I'd seen were equipped with Victory. Could well be a mix on that bike.

Good point regarding the brake nuts. I didn't pick up on that. The skewers did have me leaning towards Triomphe, but the pic just wasn't good enough. It may well be a mix, as you suggest. Still, it would be nice to get some good pics of the crankarm spider, shift levers and skewers.

Bio,

If you don't mind, how much did you pay for the bike? Does anyone out there know what the going rate for this bike is? There is one available. - Thanks

Triomphe calipers (and the one in the photo appears to have an incorrect nut on it), and Victory rear derailer and crankset. Why the mix, I do not know.

1985 catalog states that it is a mix of Triomph and Victory.
