The last of my three NOS Columbus-tubed frames (I previously posted photos of a Masi Columbus SLX-SP and a Sancineto Columbus MAX). Finally got around to taking pictures of this one, a Colnago Master Piu in Columbus-GILCO, likely from 1989-1991, I think, and in the very best color, red. Not looking for a valuation on this…only posting as a bit of eye candy. The Piu variant of the Master model features internal caliper cable guides. As I understand it, a Colnago serial number is not an indicator of manufacturing date…please correct me if I am wrong about this.
