Trek Madone SLR 9 AXS Gen 8 SRAM Red AXS Road Bike

Our Fastest and Lightest models specifically created for you who wants the best from TREK. The Madone SLR 9 AXS Gen 8 2025 is designed to fully dominate the road with light weight and aerodynamics in equal doses. It's made from our finest 900 Series OCLV carbon fiber, which is not only insanely lightweight, but also allows for aerodynamic shapes perfect for lightning-fast descents and straights. This version is ready for the podium, thanks to the top-of-the-line SRAM RED AXS E1 powertrain with power meter, Bontrager Aeolus RSL 51 carbon wheels, an aerodynamic handlebar with Trek RSL Aero stem, and RSL Aero water bottles and baskets for additional drag reduction.
