Pro Bike: Carlos Sastre's Cervélo TestTeam Cervélo R5

While his teammates have long since jumped on the aero road bandwagon with the slippery SLC-SL and now S3, Cervélo TestTeam captain Carlos Sastre has instead preferred to stay on his lighter and more comfortable R3-SL – a logical choice, seeing as how he's a climbing specialist and generally protected from the wind most of the time, anyway. This year's Tour de France, however, sees him on Cervélo's latest incarnation: the R5 (formerly known as Project California).
