I'm amused by lots of things pros do.
More to the point, pros ride slightly smaller frames to get their
bodies into a slightly more aero position. A difference in rider position will overwhelm almost any theoretical frame advantage.
By the way, the allegedly über-aero Cervelo S5 actually has a taller head tube (and a shorter fork) than many road bikes, including the R5. Care to explain?

He's been riding it in regular races as well.
While it is entirely possible he's doing it for sponsorship reasons, I can't imagine he'd ride it if he believed it would negatively influence his performance.
