The Trek Madone SL 7 Gen 8 is a race-ready road bike built to give you the best of every world. Its featherweight build lets you soar up climbs, while aero geometry cuts drag on descents and IsoFlow keeps you comfortable through the miles. To give you the best balance of price and performance, it's built with 500 Series OCLV carbon, a two-piece handlebar and stem, and Shimano Ultegra Di2 wireless electronic drivetrain that delivers clean shifts every time, all topped off with carbon wheels for extra lightweight performance.

A more economical 500 Series OCLV Carbon frame and new tube shaping shave weight where it matters most to help you fly up climbs
Carbon wheels keep weight down and performance up, so you can crush climbs and soar down descents
You get lightning-fast precision shifts that are fully customisable thanks to Shimano's Ultegra Di2 drivetrain
