Ted said:I have a 1981 Colnago frame that I use for riding that is built up with more modern components. I
originally bought the frame in 1981, but I don't know what the model was called at the time. Did
they make more than one model then? It is a 59cm c-t size frame, does anyone know the frame
angles? I think the frame is made of either Columbus SP or SL tubing. Does anybody know which?
The standard model of the era was the Colnago Super, which was a Columbus SP/SL frame. That is to
say 50cm would be SL and 63 were SP.
Like any conscientious builder, the middle sizes of a Colnago should be mixed gauge. SP/SL is
intended to allow the builder a continuum, with progressivley more SP tubes as the frame size
increases. So SL is not "better" than SP. The main tubes are 0.9-0.6-0.9 versus 1.0-0.7-1.0.
IIRC, a 1980 looks similar to this 1990, full chrome fork but without the chromed lugs, right?
