The Checkpoint ALR 4 is a versatile aluminum gravel bike designed for riders who want to explore further afield. Its modern endurance geometry and carbon fork help reduce road shock, while clearance for up to 50mm tires increases confidence and traction on rough terrain. The 11-speed Shimano CUES drivetrain, hydraulic disc brakes, and multiple attachment points for bags and accessories make it ideal for both long rides and everyday adventures.
