What is the tubing (sticker on the seat tube)?
The Master uses the shaped tubes, which this one appears to have. I'm not sure when that Mapei paint job was first used but, in my mind, when I see that paint I think year 2000-ish or later. Colnago didn't put the little "rider guy" on the top tube until '97 or '98 but I'm not sure if that has ever been a feature of the Mapei paint.
Right now, based on those pics I'm feeling about 2000-2001 Master Light
