The Colnago Nuovo Mexico bicycle was one of the early crimped frame designs from Colnago. In the early 1980’s Colnago began experimenting with crimping main frame tubes to increase stiffness. Colnago referred to these crimps as ‘ribs’ in their early brochures. Whilst I doubt the paint scheme on this bike is original, it shows the crimped frame tubing very clearly.

Special features of a Colnago Nuovo Mexico 1st Edition

I believe this frame was released in 1982 not long after the Colnago Super Profil. It was the second frame to be built using crimped tubes and is easily identified by a single crimp on either side of both the top tube and the down tube.

The word PROFIL is often associated with frames that have crimped tubes. Based on my research, it seems that all varieties of these crimped frames were essentially either Colnago Super’s or Colnago Nuovo Mexico’s. The main distinguishing feature of these 2 models is the tubing used in their construction. The Colnago Super was built using (slightly heavier) Columbus SL tubes. The Colnago Nuovo Mexico was built using a combination of Columbus SL as well as (slightly lighter) Columbus Record tubing.

Whilst there is not much information presented in Colnago brochures of that era regarding the number of crimps and where they were located in their frames. However I am able to identify this frame with a high degree of certainty because it is identical to the frame Saronni rode to win the 1982 World Championships (find out more in the next paragraph).

In 1982 Giuseppe (Beppe) Saronni won the World Championships in Goodwood, England on a bike with crimped frame tubes. This bike is on display in the Colnago museum. Read more..

It seems that the Colnago Nuovo Mexico frames did not have a chain stay bridge like all the early 1980’s Super frames did. But in the first edition of the Colnago Nuovo Mexico, the chain stays were still crimped.

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.
