BEST FOR: Gripping it and ripping it. THE TEST: The S5’s distinctive looks were polarizing: about half the testers pined for one while the other half were repulsed. But all agreed that this was the fastest aero bike we tested. It’s easy to see why. The tubes are as delicate as well-honed blades, and sleek internal cable routing further reduces drag (though fishing in new cables will turn your mechanic gray). The VWD version we tested is extra-light thanks to an enhanced carbon layup technique—hence the premium price tag. And though the Shimano Dura Ace electronic shifters worked flawlessly, they didn’t feel totally worth the extra money since they worked no better (and are only somewhat lighter) than Ultegra Di2. THE VERDICT: The fastest bike on the block. 16 lbs


What's the deal with electronic shifting, the kind you see here on the Cervelo and the Gear of the Year-winning Blue? Unlike mechanical shifters, these work under heavy loads, for zero hesitation or lost energy when you're attacking a hill or sprinting.
