The Noah might not look like a traditional aero bike. But where the Cervélo and Felt rely on radically shaped tubes to cheat the wind, the carbon Noah goes in a different direction. Vents in the fork and seatstays pull slow air away from the wheels, while rough patches on the head, seat, and down tubes direct air around the frame, much like the dimples on a golf ball. It seems to work. Though a few testers dinged the Noah for a slightly dead feel under power, they had no gripes on the way downwhoever was riding it would generally be the fastest descender in the group. $3,000 (frameset only); 16.4 lbs (56cm); ridley-bikes.com
