Why we like the Trek Checkpoint ALR 3 Gen 3
Limitless Carrying Capacity
With integrated mounts for a frame bag, racks, and fenders, this bike transforms easily from a stripped-down gravel racer to a fully loaded touring mule.
Simplified Shifting
The 1x10 Shimano CUES drivetrain eliminates the front derailleur for simplicity while offering a massive 11-48t cassette to conquer steep climbs.
Room to Roam
The generous 50mm tire clearance allows you to run chunky rubber for technical singletrack or swap to slicks for efficient pavement riding.
