Last month, the Cyclingnews tech team returned to the unassuming industrial unit that is fast becoming our second home: the wind tunnel at Silverstone Sports Engineering Hub, for the latest in the CN Labs series of empirical group tests, and this, I think, we can call "the big one."
We tested 12 of today's best aero road bikes. Not the aero all-rounders like the Tarmac SL8 or the Madone as tested last year - check out last year's superbike test here - but purebred aero machines with headtubes inspired by the Mariana Trench and radical silhouettes that, in the case of some, probably make Eddy Merckx's eye twitch with contempt.
