I recently weighed mine, which I believe is an early 80s super (with fork), and it weighed just a few grams under 2 kg.
super frame and forks 2kg
mexico frame and forks 1.85kg
These must be the weights for frame only. The Super is Columbus SL which is around 2,000g for a frame. So the Mexicos are of thinner gauge tubing than SL?
weights must be for f&f , as you say, you weighed yours at 2kg, think mexicos would have thinner gauge tubing
also the frame in question is early eighties, the only mexico then was the nuovo mexico, which had crimped tt and dt
