Trek Checkpoint ALR3 2026
The Checkpoint ALR 3 is an aluminum gravel bike built to push the limits of exploration. Its carbon fork reduces vibrations and its endurance geometry prioritizes comfort on gravel and rough roads. Its spec lets you ride everywhere on a budget, with Bontrager Paradigm wheels, clearance for 50 mm tires, a 10-speed Shimano CUES U6000 drivetrain, mechanical disc brakes, and multiple mounts for bags and other accessories.
