The Checkpoint ALR 5 Driftless is a customised-paint, high-quality gravel bike that will hold up for long, rugged miles on the road, 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 customise for your kind of adventure.
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.
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.
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.
