2025 Trek Madone SLR 9 AXS Gen 8 Road Bike

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 50 carbon wheels, a Trek Aero RSL one-piece carbon bar/stem, and RSL Aero Bottles and Cages for more drag reduction.
