Checkpoint SL 5 is a carbon gravel bike made for epic all-road adventures. It’s built with a Shimano GRX drivetrain and hydraulic disc brakes, but the defining feature of this model is the lightweight OCLV Carbon frame with IsoSpeed, a decoupler at the top tube/seat tube junction that provides additional compliance over rough terrain so you can stay stronger longer.
