Checkpoint SL 6 AXS Gen 3 is a carbon gravel bike built for far-out adventures. Its lightweight frame features comfort-focused Gravel Endurance geometry, clearance for 50mm tires (as measured), and plenty of mounts for gear and accessories. IsoSpeed technology helps soak up vibrations from rough roads, so you can float over chatter and potholes. It’s finished with a SRAM Rival XPLR AXS E1 wireless 1x13 drivetrain that’s ready to explore.
