Trek Madone SL 6 Gen 8 Road Bike in Matte Lavender Haze/Deep Smoke

Season:2026

Brand:Trek

Code:57662PUR

The Madone SL 6 Gen 8 is a lightweight aero road bike that brings elite racing tech to a lower price point.

New light and fast aero tube shaping paired with light-yet-economical 500 Series OCLV Carbon makes Gen 8 the lightest Madone SL Disc f/s ever and the ideal climbing bike.

Revolutionary new Full System Foil aero tube shapes improve airflow over the whole bike while maintaining the lightness that climbers crave. Plus, the bike’s entire rider system was meticulously designed and rigorously tested to be faster everywhere.

The race-focused comfort tech was refined to be lighter and have nearly double the vertical compliance so you can ride stronger for longer.

The Madone SL was informed by feedback from Lidl-Trek's fastest sprinters and climbers.
