The Colnago Tecnos bicycle frame first appeared in their 1996 catalogue and was still in production until the early 2000’s. This frame featured a new tube profile design and was manufactured from Nivacrom steel based on Colnago’s exclusive specification.
Originally I specified the date range of my ‘How to identify a Colnago Vintage bike’ series of articles as 1970’s to 1980’s. However I decided to include the Tecnos as it was sometimes being confused with other older Colnago frames. This page should help to identify this frame.

Special frame features of a Colnago Tecnos.
The Colnago Tecnos is easily identified by the tubing used in the top tube and down tube. The catalogue specifies the measurements of each as;
Down tube: biconical square tubing starting with 28.6mm diameter at the head tube increasing to 35mm diameter in the center, ending with 32mm diameter at the bottom bracket shell.
Top tube: biconical diameter of 25.4mm at either end, 28.6mm diameter in the centre.
This image clearly highlights the special profile of the steel tubing used for the Tecnos frame. It is described as having 5 external ribs to provide higher stiffness and stability under torsional flex stresses.
General frame features
The Colnago catalog also mentions the following features of the frame.
- Inner rear brake cable guide on top tube.
- Fittings for second water bottle cage on seat tube.
- Fork crown and lugs from Colnago Master.
- Investment cast bottom bracket shell, fork crown and drop-outs.
- Chrome plated front fork, head lugs and rear seat stays.
- Supplied with Precisa front fork (straight legs).
The following websites have a large selection scanned Colnago literature including reviews, catalogues and brochures.

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.
I have been riding and working on my own bikes for many years now. I wanted to share my experiences, knowledge and research with others. My aim is to inspire people to get involved in all aspects of this amazing sport. Cheers.
