2025 Trek Madone SL 6 AXS Gen 8 - Crimson
The 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 with a power meter, topped off with carbon wheels for extra lightweight performance.

SPECS
It's right for you if...
You want a featherweight road race bike without top-end race pricing. You're up for racing, club rides or solo spins up winding canyons, and don't want to compromise between climbing efficiency and aerodynamics. Plus, you get the wireless performance of SRAM's Rival AXS group set.
The tech you get
An ultra-light OCLV 500 Carbon frame with aero tubing and lightweight IsoFlow comfort tech. A 2x12 SRAM Rival AXS wireless electronic group set with a power meter for clean shifts under pressure. Plus, it's topped off with Bontrager Aeolus Elite 35 tubeless carbon wheels.
The final word
The Madone SL 6 AXS Gen 8 delivers race-worthy aerodynamics and climb crushing weight. It's a bona fide superbike in a more economical package, thanks to its 500-Series OCLV Carbon lay-up and workhorse AXS group set. It offers the same frame tech as its SLR sibling, like aero tube shaping and IsoFlow comfort tech, so you can stay at the front of the pack.
