"Sarroni Nuovo Mexicos (1980-1985) crimped top and down tubes"
" The visible difference between 1974-'79 Mexico and 1974-'79 Super is that the Mexico has chainstays that are not crimped at all (round-oval-round)."
there are 3 basic mexicos, mexico, nuovo and esa I have had all three and none had crimped/ribbed chain stays
perhaps a discussion for the brand thread, rather than here would be best
