I purchased a Colnago Mexico (I think) recently. I am starting to wonder now about the identity of the frame set. The stays are mostly chrome. The top tube and down tube measure 23 mm x 30 mm and 26 mm and 30 mm respectively (oval shape I guess) with a channel on either side running from end-to-end. Sort of reminds me of a flattened (top to bottom) "figure 8" in cross section. The seat tube measures 30 mm x 30 mm, no channels. I've been doing a little research and I'm starting to think that this might be the "Oval CX" frame set Colnago made for a brief time. If it is, when was it introduced? Did the Mexico or Nuovo Mexico have such a frame set? How rare is this? (By the way, the fork is totally chrome.)

No pics. Problem solved. I found an earlier post under "Classic and Vintage; What's It Worth?" where a similar problem was answered by Picchio Special who I beginning to see is the forum expert on Colnago's. In this case, pics were provided and it matches my bike exactly. FYI it's a Nuovo Mexico frameset.
