TREK Checkmate SLR 9 AXS (2026)

Checkmate SLR 9 AXS is the race-ready gravel bike designed for riders who want just one thing: to go faster, everywhere. The ultra-light carbon frame with Full System Foil profiles slices through the air and turns every watt into pure speed, making it our fastest gravel bike ever .

IsoSpeed technology filters out vibrations from the roughest gravel, so you can push harder for longer without fatigue. The new gravel racing geometry puts you in an aggressive yet efficient position: ready to attack without burning through your energy before the finish line.

The components are state of the art: high-profile carbon wheels for maximum responsiveness and smooth rolling, and a SRAM RED AXS XPLR wireless drivetrain, the latest evolution in ergonomic, precise and customizable shifting.

Whether you’re targeting the toughest gravel races or simply want a fast, lightweight bike to dominate gravel, white roads and tarmac, Checkmate SLR 9 AXS is the ultimate weapon for those who won’t settle for sitting in the bunch.
