Trek Madone SLR 9 AXS Gen 8

Madone SLR 9 AXS Gen 8 is built for dominating the roads with equal parts light weight and aerodynamic speed. It's crafted from our highest-level 900 Series OCLV Carbon that's not only insanely light, but delivers aerodynamic shapes for crushing descents and straightaways. This build comes ready to win with a top-level SRAM RED AXS E1 drivetrain with a power meter, Bontrager Aeolus RSL 51 carbon wheels, a Trek Aero RSL one-piece carbon bar/stem, and RSL Aero Bottles and Cages for more drag reduction.

Our lightest Madone Disc ever

New light and fast aero tube shaping paired with our best 900 Series OCLV Carbon makes Gen 8 our lightest Madone Disc f/s ever and as light as the Émonda f/s.

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.

Designed for the world’s best

Madone SLR Gen 8 is raced and loved by Lidl-Trek's fastest sprinters and climbers and the only bike they need for race day.

One-piece Aero RSL bar/stem

A new one-piece bar/stem is lighter, more aeryodynamic, and more ergonomic than the previous version. Plus, the hoods are 3cm narrower than the drops so you can adjust your positioning to prioritize aerodynamics (in the hoods) or power (in the drops).

RSL Aero Bottles and Cages

Included RSL Aero Bottles and Cages were specifically designed along with the whole rider system to help make Madone even faster.
