The Checkpoint SL 5 is a carbon gravel bike made for epic adventures. It's built with lightweight OCLV Carbon, a 2x12 Shimano GRX drivetrain, terrain-smoothing damped IsoSpeed, nimble yet stable progressive geometry, internal storage and loads of mounts. All of that adds up to a rad gravel bike capable of crushing the longest, roughest rides and the most ambitious bikepacking trips.
