How to identify a Colnago Nuovo Mexico from a Colnago Super (profil)

How to identify a Colnago Nuovo Mexico

I get a fair amount of requests to appraise vintage Colnago roadbikes,(which is always a pleasure), and amongst those fine steel steeds have been a number of  questions regarding the Colnago Nuovo Mexico model, (circa 1984).

More often than not the owner has one of these, which were more common, the Colnago Super (profil), which can be identified from one crimp either side and center on the top tube, one either side and center on the down tube, and inside the chain stays

a Colnago Nuovo Mexico has two crimps either side and center on the top tube, 2 crimps off center either side of the down tube (so dt has 4 crimps in total!) , and none inside the chain stays

This example is Mr ‘ Beppe ‘ Saronni’s Del Tongo Team circa 1982 Goodwood winning Super

You can see it has one rib on the top tube ( one either side , two in total)

And only two ribs on the down tube , predating the circa 1984 release of the Nuovo Mexico with 4 down tube ribs located off center …

This is a circa 1984 Super ‘profil’ , same era as the Nuovo Mexico was launched ..

This frame is the same age and colour , but is a Nuovo Mexico

Two ribs in the top tube ..

And 4 off center in the down tube
