Description
Trek Checkpoint ALR 4 Gen 3 Gravel Bike
The Trek Checkpoint ALR 4 Gen 3 Gravel Bike is an aluminium gravel bike designed for riders looking to explore beyond the tarmac. Its modern endurance geometry delivers stability and comfort on rough terrain, while generous tyre clearance up to 50 mm offers extra grip and control on loose surfaces.
Fitted with an 11-speed Shimano CUES 8000 drivetrain, hydraulic disc brakes and Bontrager Paradigm wheels, it provides smooth shifting and confident stopping power. A lightweight carbon fork helps reduce road buzz, and multiple mounts for bags and accessories make it a practical choice for bikepacking, long adventures or weekend escapes.
