Orbeau - Carpe H30 $900
Personally I ride a dusty old clunker the 7km to work. Keeps me fitter than the above, that I still really want. I don't get a lot of the lycra clad cyclists. I see them riding in packs, talking. If you're holding a casual discussion you're not actually exercising. You're kidding yourself.
The biggest factor in a bicycle is probably its engine.
Not sure how much the internal hub weighs on the Avanti of this post. Could be a factor, or not.
