Hello Colnago Mexico Fans (experts?),
Does any one know how long the Colnago Mexico's were produced (ex: year started and stopped)? Is there a way of telling if it is a true Mexico, besides on bending the tubes by feel while the owner is not watching? Thanks for any help you can give me because I wanted to determine one particular frame that I have that is so super light, without having to get an oilfield friend over with his cathodic protection metal thickness indicator equipment. Many thanks to you all and hope you all have many happy and safe cycling experiences.
