Cervélo has been producing arguably the most coveted race frames in the world for a few years now, so we weren't surprised that the carbon S3, the Canadian company's new flagship model, was a standout. "If I had the money," said one tester, a pro who'd just finished sprinting up a steep, short climb, "I don't think there's any other bike I would buy." The S3 takes the stiff, aero front triangle of the popular Soloist frame and merges it with a rear triangle inspiredby Cervélo's R3 comfort-performance bike. The result is a frame that manages to be both stiffer and more comfortable than the Soloist. $4,500 (frameset only); 15.5 lbs (56cm); cervelo.com
