Discover how light, fast and efficient a bike can really be! Trek's Madone SL 5.9 features the same feathery frame enjoyed by the Discovery Channel team. Designed with input from Lance Armstrong, the frame is incredibly stiff and aerodynamic, too. The SL stands for Super Light, and combined with the fast-rolling Bontrager wheels and flawless-shifting-and-braking Dura-Ace 30-speed components, this bike positively flies down the road and flattens the climbs.
