Trek Checkpoint ALR 3 Gen 3 Bike

Checkpoint ALR 3 is an adventure-ready aluminum gravel bike built for exploring anywhere.

Its modern endurance geometry keeps you comfortable over gravel roads or potholes, while a carbon fork helps cut down the road vibrations. It's spec'd to go anywhere without breaking the bank, with Bontrager Paradigm wheels, clearance for 50mm tires, 10-speed Shimano CUES 6000 shifting, mechanical disc brakes, and tons of mounts for bags and accessories.

This bike is best for:

  • Upgrading bike owners — The Checkpoint ALR 3 Gen 3 provides a great upgrade point for current bike owners with its enhanced specifications, features, and reliability.

  • Gravel riding — The included Bontrager Girona tires are a lightly treaded fast-rolling gravel tire that’s perfect for speed and grip in hardpacked and mixed conditions. The carbon fork helps with road vibration over gravel roads or potholes.

  • Active riding — The active road geometry gives you a forward position for efficiency and comfort.

  • Commuting — Provides a solid choice for commuters with great reliability and maneuverability for everyday riding.

  • All-in-one versatility — The Checkpoint ALR 3 provides an all-in-one choice for those looking for a versatile bike capable of adapting to the rider's preference, whether on the road for commuting, fitness, or rail trail riding.

Tech Features

  • Mounts Galore

    The new Checkpoint ALR is equipped to carry everything you need with mounts on the frame and fork for front and rear racks, fenders, and Adventure Top Tube, Frame, and Triangle Bags. Plus, the new frame was optimized to fit extra hydration in addition to all your bags.

  • Gravel Endurance Geometry

    Designed with Gravel Endurance geometry with a higher stack and shorter reach for improved comfort and control on long days in the saddle.

  • Increased Tire Clearance

    Designed with 50mm (or 29 x 2.0)* tire clearance for more grip and comfort on challenging terrain. *As measured

  • Suspension Fork and Dropper Post Compatible

    Compatible with a suspension fork* and dropper post for riders tackling technical descents or seeking more aggressive off-road performance. *Available on all sizes except XS frames

  • Alphanext - Low Emission Aluminum

    Starting in 2024, Trek began removing high-emission aluminum from their manufacturing and replacing it with low-emission aluminum made with renewable energy. By October 2025, nearly every alloy bike Trek makes - this one included - has made the switch, driving a major drop in Trek's footprint.
