It offers similar aero benefits to the pricier Madone SLR Gen 8, but with a more economical OCLV 500 Carbon layup 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 customizable, it's decked out with SRAM's Rival AXS electronic groupset, topped off with carbon wheels for extra lightweight performance.

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 groupset.

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 groupset for clean shifts under pressure. Plus, it's topped off with Bontrager Aeolus Elite 35 tubeless carbon wheels.

The final word

Madone SL 6 AXS Gen 8 delivers race-worthy aerodynamics and climb crushing weight. It's a bonafide superbike in a more economical package, thanks to its 500-Series OCLV Carbon layup and workhorse AXS groupset. 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.
