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, hydraulic 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!

Sizing & fit
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
