Madone SL 6 Gen 8 is a lightweight aero road bike that brings elite racing tech to a lower price point. It offers similar aero benefits to the pricier Madone SLR Gen 8, but with a more economical OCLV 500 Carbon layup and two-piece cockpit with hidden cable routing. Its built to race with geometry that keeps you comfortable on the climbs and perched for the attack. A Shimano 105 Di2 electronic groupset keeps the price down without sacrificing lightning-fast electronic shifting. Plus, its topped off with carbon wheels for extra lightweight performance.
- Revolutionary Full System Foil aero tube shapes redefine what fast looks like and help optimize aerodynamics around the whole bike
- 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 shifts that stay crisp and clean thanks to Shimanos Di2 tech trickling down to their 105 groupset
- Lightweight, race-focused IsoFlow comfort tech helps you ride stronger longer without sacrificing weight or aerodynamics
- This bike comes set up tubeless a first in Trek performance road history
Our lightest Madone SL Disc ever
New light and fast aero tube shaping paired with light-yet-economical 500 Series OCLV Carbon makes Gen 8 our lightest Madone SL Disc f/s ever and the ideal climbing bike.
Redefines what fast looks like
Revolutionary new Full System Foil aero tube shapes improve airflow over the whole bike while maintaining the lightness climbers crave. Plus, the bikes entire rider system was meticulously designed and rigorously tested to be faster everywhere.
80% more vertically compliant IsoFlow
We refined our race-focused comfort tech to be lighter and have nearly double the vertical compliance so you can ride stronger longer.
Rooted in racing
Madone SL was informed by feedback from Lidl-Treks fastest sprinters and climbers.
Adjustable aero cockpit
Madone Gen 8 features hoods that are narrower than the drops so you can adjust your positioning to prioritize aerodynamics or power. Plus, the two-piece design lets you quickly and easily dial in your fit.
