You'll never see the SuperSix EVO Black Inc. on the street. You probably won't even see it in a local road race. This is Cannondale's chef d'œuvre, built with only the best components, top to bottom—it's a $11,920 piece of carbon ridden by the fastest humans on Earth.

This SuperSix is fully decked out with Enve everything: Wheels, stem, bars, and seatpost, along with Chris King hubs and Shimano Dura Ace 9000 shifter and brakes. Incredibly, the frame itself weighs less than six sticks of butter—or about the weight of a bidon, if you prefer your weight in Tour de France-speak.

But surprisingly enough, the bike's most interesting piece is the saddle. Made by Fabric, a company recently acquired by Cannondale, this saddle is constructed out of one full piece of carbon overlaid with buffalo leather. There's no other saddle like it in the world.

This apex of technology will most likely never make a place in your home—but fits right in at the Tour de France. [Cannondale]
