For 4,000 dollars I would rather have a Trek Madone 5.5 Pro...
It would have a lot more carbon fiber, and I would bet that 4,000 dollars that it is better carbon fiber as well.
Why don't these have sapphire lenses or something like that? For 4,000 I would expect every possible feature. They should also have some sort of liquid crystal layer inside the lens so they have variable dimming for different light levels.
