Trek Madone SLR 9 AXS Gen 8 (2025)
Couldn't load pickup availability
The Madone SLR 9 AXS Gen 8 is built to dominate the roads with its lightness and aerodynamics. It is made with our top-level OCLV 900 Series carbon, which is not only incredibly light but also shaped with aerodynamic profiles to excel on descents and straightaways. The lightweight frame with IsoFlow technology ensures Madone never sacrifices comfort for speed. The top-of-the-line SRAM RED AXS drivetrain, carbon wheels, one-piece Trek Aero RSL carbon handlebar/stem, and RSL Aero bottle cage system to further reduce drag make this bike a perfect candidate for victory.
