Mounts for bikepacking: Frame and fork mounts for racks, fenders, and frame bags let riders load up for multi-day trips or daily commuting.
50mm tire clearance: Fits tires up to 50mm (or 29 x 2.0) for extra grip and comfort on technical terrain.
Suspension and dropper compatible: Accepts a 40mm travel suspension fork on all sizes except XS and works with a dropper post for more confident descents.

PERFECT FOR

Riders who want a tough, mount-friendly aluminum gravel bike that can handle long gravel days, light bikepacking trips, and everyday commuting without a complicated drivetrain to maintain.

Why we like the Trek Checkpoint ALR 3 Gen 3

Comfort-focused frame geometry

The Checkpoint ALR shares the same gravel endurance geometry as its carbon sibling, with a shorter, higher reach that keeps riders relaxed and in control over long days in the saddle.

Carbon fork for smoother rides

The full carbon fork takes the sting out of rough roads and gravel, pairing with the frame's tire clearance to let riders run wider rubber for extra comfort and grip.

Built-in versatility for bags and racks

Mounts on the frame and fork support front and rear racks, fenders, and frame bags, so the bike adapts easily between bikepacking trips and round-town errands.

Trek's journey began in 1976 when founders Dick Burke and Bevil Hogg, fueled by a shared passion for cycling, set out to create a brand that went beyond the ordinary. Starting in a southern Wisconsin barn, Trek emerged with a mission to craft extraordinary bikes. Born out of a culture of craftsmanship and rebellion, Trek challenged the convention that only European bikes could be great. Today, Trek stands as a symbol of relentless progression, innovation, and a commitment to building bikes that people love.
