Subject: [CR] Help with unique Colnago question

Hello Vintage Cycling Friends,

I have a 78 Colnago Mexico and the frame is so light with the Columbus lightweight thin walled tubing. The issue, which may sound strange, is that the seat tube is a tube that accepts the 26.8 post only. After many emails and people questioning me, there are numerous comments about this frame really being a Mexico. The frame is much lighter than the Super in the same size, matched frame for frame on a scale. Everyone I have confronted with the information has stated that Mexico's have a 27.2 post. I have a panto Mexico post and it is a 27.2. Could anyone raise an explanation why this 26.8 is or how it is possible? There has got to be some Colnago intelligence with this CR site. All the indicators are there for this being a Mexico. 1) The extra light weight 2) The non crimped chain stays 3) The faint remains of pieces of a Mexico decal (this is a joke and is no indicator of proof because decals are everywhere)

If anyone could please help with some data or recommendations, I would certainly appreciate it.

Thank you.
