Hello and although a long time ago, I am very happy you started this thread on the COLNAGO "Super Sprint", Nenad. I only found it recently after a great deal of conversation online and catalog research. I believe my COLNAGO frame may be a variant of the same range of 'lower cost' frames (using COLUMBUS "SL + CROMOR" tubes) built in the late 1980's. I also only recently discovered that COLNAGO made four (?) bicycles for the 1980 MOSCOW Olympics as the "Mexico Quartet" all having the rear brake cable routed through the Top tube. On those bicycles only they also mounted the rear brake caliper on the inside of the rear triangle, apparently in the interest of aerodynamics.

Cheers!
