Our fastest and lightest unite

Insanely aero. Impossibly light. Wildly thrilling. The Madone was designed with input from the world’s top racers to be the best wherever you ride it. Whether you’re powering up climbs or sprinting across the finish line, the Madone fuses our fastest and lightest into one ultra-lightweight, race-ready superbike.

Built with Trek’s 500 series aerodynamic carbon frame and equipped with Shimano 105 Di2, the Madone SL 6 Gen 8 delivers electronic shifting, IsoFlow comfort and tubeless carbon wheels, ready for fast-paced rides and challenging climbs.

Key Features:

  • 500 Series OCLV Carbon frame with aero shaping and IsoFlow comfort tech
  • Madone Gen 8 full carbon fork with tapered steerer and internal routing
  • Shimano 105 Di2 2x12-speed drivetrain with trickle-down shifting tech
  • Shimano hydraulic disc brakes with 180/160mm RT70 rotors
  • Bontrager Aeolus Elite 35 carbon wheels with R3 700x28mm tyres
  • Tubeless-ready setup for lower rolling resistance and fewer punctures

The Trek Madone SL 6 Gen 8 proves that race-ready technology doesn’t have to come at a premium. It shares the same aero-focused frame design as Trek’s models, using 500 Series OCLV Carbon and the latest Full System Foil tube shaping to improve airflow across the entire bike and rider system. This means better speed without compromising the balance and ride feel.

Where the Madone SL 6 really stands out is in its IsoFlow seat tube design—a unique feature that increases compliance by flexing under the saddle, absorbing road vibrations and keeping you fresher on long rides. It’s Trek’s way of blending race geometry with everyday comfort, ideal whether you're sprinting for the line or pacing a solo effort.

The standout component is the Shimano 105 Di2 12-speed groupset, offering wireless electronic shifting with smooth, lightning-fast gear changes. Thanks to Shimano’s trickle-down technology, you get the same shifting feel and performance found in their top-end systems, now in a more accessible package.

Shimano hydraulic disc brakes with RT70 rotors (180mm front, 160mm rear) ensure confident braking no matter the weather, while Bontrager Aeolus Elite 35 carbon wheels deliver climbing efficiency, fast acceleration and stability at speed. These come set up tubeless with Bontrager R3 Hard-Case Lite 700x28mm tyres, reducing rolling resistance and offering greater puncture protection.

The bike is finished with a mix of lightweight and race-optimised finishing kit, including a Trek RCS Pro stem, Bontrager Comp alloy bars, and a Madone aero carbon seat post. It’s a build that puts performance first while keeping value in mind.

Whether you’re racing at the weekend or stepping up your everyday road riding, the Madone SL 6 Gen 8 brings cutting-edge frame tech, wireless shifting and aero efficiency together in a superbike-style package without the superbike price tag.
