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.

About Trek
The best bike, ridden everywhere.
Founded in a Wisconsin barn in 1976, Trek has grown into one of the world's most recognised bicycle brands without losing the obsession that started it all: build the best bike, ride it further, share it with everyone.
Trek believes the bicycle is a simple solution to many of the world's most complicated problems. Every bike Trek builds — from the Madone race weapon to the Marlin trail bike — is made with that conviction. More riders, more often, on better bikes.
