TREK CHECKPOINT ALR 5

Checkpoint ALR 5 is the best value gravel bike in the lineup. It's a high-quality build that will hold up for long, rugged miles on pavement, dirt, and even the most treacherous gravel roads. A wealth of features like nimble-yet-stable progressive geometry, loads of mounts, plus a GRX drivetrain make it easy to customize for your kind of adventure.

It's right for you if...
Unlike the pure roadie who measures watts and weighs out meals, you favor epic off-road adventures that probably end with a beer and a burrito. But that doesn't mean you'll compromise on performance. You expect to get a lot for your hard-earned dollar, including quality, versatility, durability, and a ridiculous amount of fun.

The tech you get
A sturdy aluminum frame with a progressive geometry that's stable at speed and efficient when you're grinding up a climb, hidden cables that won't interfere with bags, rack and fender mounts and integrated frame bag mounts, a 2x11 Shimano GRX drivetrain with lower gears for grinding up hills or through rough gravel, hydraulic disc brakes for all-condition stopping power, tubeless ready rims, and wide 700x40c gravel tires for added stability and traction.

The final word
If the amount of adventure you can get per dollar spent is a priority for you, you won't do better than Checkpoint ALR 5. Quality parts, a durable alloy frame, and a wealth of features like extra tire clearance and customization options— so you can confidently take on bigger, better adventures.
