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 the fishnet paint scheme on this bike is not original, it is certainly very beautiful.

Special features of a Colnago Nuovo Mexico 2nd Edition

I believe this frame was released around 1984 not long after the first version of the Colnago Nuovo Mexico. It was the third frame to be built using crimped tubes and is easily identified by a single crimp on either side the top tube and two offset crimps on each side the down tube (total of 4 crimps on 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 the crimping on this frames does NOT match 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..

Other features of this model.

It seems that the Colnago Nuovo Mexico frames did not have a chain stay bridge like all the early 1980’s Colnago Super frames did. The second edition of the Colnago Nuovo Mexico generally did not feature crimped chain stays.

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.
