Feel the Difference with Trek Madone SLR 9 Gen 8 2025

The Madone SLR 9 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 Shimano's top-of-the-line Dura-Ace Di2 wireless drivetrain, 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.
