The Colnago Sport was an entry level bicycle manufactured from the late 1970’s to the 1980’s. The lower price point made it more accessible to enthusiasts when compared with the top-tier Colnago racing bikes of the era like the Colnago Super.

How to identify a Colnago vintage bike.
Whilst the Colnago Sport was not listed in any of the official Colnago literature of that era, online research indicates that it was sold as a complete bicycle, specifically for the German and North American markets.
Interestingly, there is considerable evidence to suggest that Colnago did not actually manufacture this frame. If you look closely at the seat tube decal on this frame shown below, you will notice it says ‘Product of VeloSport’.
Apparently it was quite common in the 70’s and 80’s for Italian bicycle companies to outsource frame building to other manufacturers when demand was exceeding their own manufacturing capacity.
This frame was built using round tubes. Although there is no Columbus decal on this frame, I found information online that suggests the main triangle of these frames was constructed uisng Columbus Aelle tubing. As expected this tubing was a lower priced product designed for amateur and touring cyclists. It was built of cold-drawn, microalloyed-steel (CMn) with thin wall tubing which reduces weight. The tubes were straight gauge with no butting.
Whilst I don’t have any geometry information for this frame, I expect it probably shared a similar racing geometry to the Colnago Super frame.

The following images are based on a frame circa 1980’s and you will notice that there are no Colnago or Clover stampings on the frame. So the only Colnago branding on this frame is found on the decals.

Please remember that this information is only to be used as a guide.
I consider myself an enthusiast, not an expert. The information I have presented in this article is based on my many hours of online research.
In addition, there will always be frames that don’t quite match the characteristics of a particular model as they could have been a custom build, prototype etc. Note: forks can also be swapped between different frames.
