    Trek Men's Checkpoint AL 4 Gravel Bike

    Checkpoint AL 4 is an ideal entry point to the world of gravel riding. It's built with a lightweight aluminum frame and a durable parts group that won't quit on you as your skills advance.

    It's right for you if...
    Your idea of the perfect ride includes chasing the sunlight through a car-free landscape on a long dirt road. You ride for the experience of it, but you also need your bike to have the versatility to take on city commutes and daily around-town rides.

    The tech you get
    A 200 Series Alpha Aluminum frame with massive tire clearance, a carbon disc fork, 12mm thru axles, a 2x10 Shimano Tiagra drivetrain, fender and rack mounts, Tektro mechanical disc brakes for all-weather stopping power, Tubeless Ready wheels, and 700x32 Bontrager R1 Hard-Case Lite tires.

    The final word
    If you're looking for adventure off the beaten path without breaking the bank, Checkpoint AL 4 is a great choice. This value-minded ride is built for epic gravel rides, but it's equally at home on city streets, your daily commute, and more!
