Trek Madone SL 6 Gen 8  Road Bike For Sale

The Trek Madone SL 6 Gen 8 is a lightweight aero road bike that makes elite racing technology affordable. It offers similar aerodynamic advantages to the higher priced Madone SLR Gen 8, but is based on a more affordable 500 Series OCLV carbon layup and a two-piece cockpit with internal cable routing. Built for racing, its geometry ensures a high level of comfort on climbs and enables aggressive attacks. The electronic Shimano 105 Di2 groupset keeps the price low and the shifting performance high. The carbon wheels contribute to the super-light performance of the bike.

Why you will love it

  • The revolutionary Full System Foil tube profiles ensure an extremely fast look and give the entire bike unprecedented aerodynamic efficiency.
  • The more affordable 500 Series OCLV Carbon frame and new tube profiles save important weight for superior climbing performance.
  • For efficient climbs and confident descents, the carbon wheels reduce weight and increase performance.
  • Thanks to Shimano’s 105 Di2 group with high-end technology, you benefit from crisp and clean gear changes.
  • Lightweight, race-focused IsoFlow comfort technology helps you pedal harder for longer.
