From the department of useless facts: My current build in progress is a 1989 Schwinn Circuit with Columbus SL/SP tubing with the OE Tange fork. I was surprised to see this combo weighs 8 tenths (0.8) of a pound more than my Raleigh USA frameset with Reynolds 531c. Same scale was used to measure. In fairness, the Schwinn is bigger with a 59cm seat tube vs. the Raleigh with a 56cm. Still, it's a little disappointing to know this Schwinn "lightweight" with Columbus SL tubing is nearly a pound heavier before I hang the first part.
The frames:
Raleigh frame: 4.27lbs + fork 1.45lbs = 5.72lbs
Schwinn Circuit frame: 4.75lbs + fork 1.8lbs = 6.55lbs
The Circuit frame has only 3 main tubes that are Columbus SL. The rest is Tange I believe. Still a respectable weight on a great frame. I had one and loved the way it rode and handled.
