RadioShack Nissan Trek will be riding the Speed Concept 9.9 at this year's stage 5 in Bakersfield. Originally debuted during the 2011 campaign, the bike remains unchanged this year. Why change a perfectly good mix? The 9.9 Speed Concept has received praise from everyone that's raced it. Made in Wisconsin from Trek's 600 Series OCLV, the team bikes are outfitted with complete Shimano Dura Ace Di2 drivetrain and Bontrager components. They'll also be riding Bontrager's new Aeolus 9 D3 Tubular front wheels and a full disc in the rear.

RadioShack Nissan Trek's Speed Concept is no longer only team issue, you can buy the exact same bike the team uses through Trek's Project One program.
