The Trek Madone SL 6 AXS Gen 8 is a lightweight aero road bike that brings elite racing tech to a lower price point. It offers similar aero benefits to the pricier Madone SLR Gen 8, but with a more economical OCLV 500 Carbon lay-up and two-piece cockpit with hidden cable routing. It's built to race with geometry that keeps you quick on the sprints yet in control on fast descents. For clean shifts that are fully customisable, it's decked out with SRAM's Rival AXS electronic group set, topped off with carbon wheels for extra lightweight performance.
