I was wondering if any one could tell me what Colnago frame sets were offered in the mid eightys. If there was a reference data base available on the net that some one knew of that would be great too.

Bicycle frame technology wasn't as varied in the 80s as it is now. High end frame builders used either Colombus SL or Reynolds 531 until the mid eighties, when Colombus brought out SLX and Reynolds came up with 753, thinner by .2 mm than 531, and slightly lighter.

During the early 80s, Colombus SL tubing, CRMO, 1.0 mm at ends, .6 mm in middle, held together with investment cast CRMO lugs, usually short point, was the way virtually all top grade Italian frames were built, including Colnago.

The only other tube choice was Reynolds 531, which English, American, and Belgian frame builders used. Eddy Merckx built with Reynolds 531, same weight as SL, except it was formulated using manganese instead of chromium. Chromium was viewed then as stiffer than manganese.

Racers, those who Colnago built for, tended to like SL; tourers liked 531, considering 531 to be more resilient than SL, a similar property attributed to today's titanium frames. Klein was the only builder using aluminum, and carbon fiber wasn't around yet. Steel was still king.

By the mid eighties, Colombus introduced SLX tubing, same as SL, with the addition of rifling on the downtube and seattube where they join the bottom bracket.

So Colnagos built in the 80s were SL or SLX steel tubes, copper brazed with investment cast lugs, had SL forks with semi-sloping or fully sloping investment cast crowns. They had 39 inch wheelbases, fairly steep head angles like 74 degrees, and handled as good as, or better than, the best road bikes of today.

Thanks for the reply. The info on frame set material is good and now I recognise that is good to know info too. But what I was looking for was what were the model names Colnago was offering back then. Victory, Master piu, Superissimo, and what were the intended aplications.

They were all serious racing bikes like they are today. The Victory was an SL frame put together with investment cast lugs, had a chromed, semi sloping fork crown, upright angles and rode like a rocket. It had Campy "Victory" component grouppo on it, and was intended for the US market: aggressive club riding and criteriums, in keeping with Colnago's thing, racing.

At one point about 1990, he used straight fork blades and squashed the down and top tubes, which presumably stiffened the handling. One such model was the "Conic," I think, but now we're in the early 90s.

Thanks, I'm interested in tyring to find one with a straight fork. I've seen a Victory and it has a curved fork. Did certain models come with the straight fork or was that an option?

Thanks again.

I think the Conic, which Colorado Cyclist offered, among others, came out in 90 or 91, about the same time Colnago went to straight forks, and started squashing tubes. Tony Rominger rode this vintage Colnago. Was that earlier than 90? Anyway, once Ernesto went to straight blades, you didn't see any more Colnagos with curved forks.
Thx Guido good info.9WorCP

I'm keeping that run down in my note book.
