Trek's Madone 6 Series is race-bike royalty with an aero advantage. Hand built in the USA from Trek's 600 Series OCLV Carbon, this king of the concrete boasts Trek's super-aerodynamic KVF tube technology to smooth airflow from tip-to-tail and effortlessly turn pedal power into speed. The Madone also features Trek's stiff, beefy BB90 bottom bracket for optimal power transmission, their tapered E2 front end so you slice through corners with pinpoint precision, and an integrated and adjustable seatmast for outstanding compliance. Plus, the Shimano Ultegra Di2 electronic drivetrain offers practically telepathic shifting and the blazing-fast Race Lite wheels are an absolute dream to ride.
