Product Details

Trek Checkpoint ALR 5 Gen 3 Gravel Bike

The Trek Checkpoint ALR 5 Gen 3 Gravel Bike is an aluminium adventure bike built to go wherever the road or trail leads. Its modern endurance geometry delivers confident handling and lasting comfort over long distances, while a carbon fork helps absorb vibrations from rough terrain.

With 50 mm tyre clearance, there's ample room for extra grip and control on loose or uneven surfaces. The bike is equipped with a 12-speed SRAM Apex XPLR drivetrain for reliable, gravel-specific gearing, along with powerful hydraulic disc brakes for confident stopping in all conditions. Tubeless Ready Bontrager Paradigm wheels and multiple mounting points for bags and gear make it ideal for bikepacking, gravel races or all-day exploration.

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.
