olmo mexico.
 

anyone familiar with an olmo frames. what about a track frame labeled olmo*mexico on the down and seat tubes. says competition on the chainstays. has almost panto'd into the caps on the seatstays like late 70's frames and a nice flat fork crown...

is mexico just a model name or was the frame maybe made in mexico?

the bb look like a cinelli bb but the flat part doesn't say cinelli, it's just blank...

Look at bulgier.net for the olmo catalogs...the competition was Olmo's bread and butter line. They made several grades of bike using different parts and, sometimes, tubing. I don't know about the Mexico tag, but during that timeframe Mexico was the place to go to set the hour record (probably still is, but the UCI has screwed up the rules so much it seems that no one wants to pursue it any more). For instance, Colnago Mexico was a special road bike that was considerably reworked for lightness (special tubing, parts whittled to nothing). Maybe the Mexico moniker indicates that?
