The tech you get

A stout 300 Series Alpha 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 1x12 SRAM Apex drivetrain for grinding up hills or through rough gravel, hydraulic disc brakes for all-condition stopping power, tubeless ready rims, and wide Bontrager Girona Pro 700x42c 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, Checkpoint ALR 5 is your ride. 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.
