I've been looking at a lot of the coverage of the Tour de France. All of the attention is on the cyclists, and no attention whatsoever on the cycles. Even in photographs or videos, they are so far away, or the bikes are moving by so fast, you can't tell what they are riding.
I know I definitely can't afford whatever kind of bike they are using, and it would be horribly impractical for me to ride one since I'm commuting, not racing. I'm just very curious as to what is the top of the line in terms of bikes. When I look at high end bikes in shops or online I can't tell if they are actually superior or if they are just loaded with expensive gimmicks.
What frames, brakes, seats, gears, tires, etc. are the world's top competitors using?
