Trek Checkpoint ALR 3 Gravel Bike
The Trek Checkpoint ALR 3 Gravel Bike is a versatile aluminium gravel bike built for adventure and exploration. Its modern endurance geometry offers confident, stable handling and long-distance comfort across rough surfaces, while the carbon fork helps absorb vibrations from gravel roads and uneven terrain.
Equipped with 10-speed Shimano CUES 6000 shifting, mechanical disc brakes and Bontrager Paradigm wheels, it delivers reliable performance at a great value. With generous tyre clearance for up to 50 mm and multiple mounting points for bags and accessories, the Checkpoint ALR 3 is ready for bikepacking trips, all-day gravel rides or daily commuting.
