Two Peugeot "Course" bicycles, nearly identical, but made from different tube sets. One, the bigger of the two, a 56cm ride and made from Carbolite 103, weighs 21lb 7oz.

The other, a Reynolds 531 53cm bicycle, comes in at 22lb 13oz.

The results surprised me, and does tend to support something, I have believed for quite a while. Carbolite 103 offers a pretty decent ride quality.
