2026 Madone SL 5 Gen 8 Road Bike
-
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 bike’s 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-Trek's 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.
-
Add-on aero bottles to make your whole bike faster
Add-on RSL Aero Bottles and Cages were designed with Madone Full System Foil aero shapes to make the whole rider system even faster.
-
Shimano 105
With shift technology inherited from mechanical Ultegra and Dura-Ace, Shimano 105 gives you top-shelf shifting at a budget friendly price. Whether you're commuting year-round or training for the big race, Shimano 105 is a workhorse drivetrain that won't hold you back as you grow in the sport.
-
Don’t forget your pedals
This bike doesn’t come with pedals because you’ll have a better time on your new bike if you choose your own. See the pedal guide to find the best pedals for your riding style. We recommend clipless road pedals for control and efficiency.
