Nothing wrong with Monocoque. It's never as light as a tubular structure though.
I wouldn't be using Biomega as an example of good engineering though. That's what happens when Industrial Designers' egos are allowed to run amok.

Get your hand off it Mac Newson you ******! Hide the cableing but then not care about standover clearance for shorter people, and conveniently ignore the biggest torsional loading experienced in a bicycle frame - that between the head tube and the bottom bracket - by attaching the 'top tube/boom tube'.......to the seat tube?
Idiotic.
