The 2011 Specialized is ugly.
Regarding sloping top tubes--some do it by making the head tube longer and some do it by making the seat tube shorter. Well, with some it's also a combination of the two.
The head tube height of the Roubaix is clearly over the top, and the curves and tapers of the top tube only make it look sillier. The Scott CR1/Speedster, Trek performance fit, and Cannondale CAAD proportions, though generic looking, are more about what a road bike should be. It's curious that head tubes on the race-oriented Tarmac are still higher than what's on these bikes, but I'm seeing that most pros and serious riders handle this by sizing down.
With their TCRs, Giant works the other way. Head tube heights are conventional but the seat tube is shortened. I used to hate all sloping top tubes, but I always made a grudging exception for the straight, minimalist look of the TCR.
It's still a far cry from my holy grail, though, a late-70s Confente.
