Note: Trolling or argumentative comments will be removed as they are counter-productive.To me, it’s a testament to Colnago’s effort to do something truly special, and that commitment to offer something special shows in their stock frames as well.Ĭolnago’s C40 has been widely regarded as the frame to have.

I wanted to share my experiences, knowledge and research with others. I have been riding and working on my own bikes for many years now. Note: forks can also be swapped between different frames. 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. The information I have presented in this article is based on my many hours of online research. I consider myself an enthusiast, not an expert. Please remember that this information is only to be used as a guide. I have listed the following website pages as general references.

The following images are based on a frame circa 1980’s and you will notice that there are no Colnago or Club stampings on the frame. Features of an Colnago Sport (Circa 1980’s). There are 2 bikes featured in this identification guide, the first bike is from the 1980’s, the second is from the 1970’s. 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 tubes were straight gauge with no butting. It was built of cold-drawn, microalloyed-steel (CMn) with thin wall tubing which reduces weight. As expected this tubing was a lower priced product designed for amateur and touring cyclists. 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. If you look closely at the seat tube decal on this frame shown below, you will notice it says ‘Product of VeloSport’.Īpparently 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. Interestingly, there is considerable evidence to suggest that Colnago did not actually manufacture this frame. 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. 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. The Colnago Sport was an entry level bicycle manufactured from the late 1970’s to the 1980’s.
