It's right for you if...
Unlike the pure roadie who measures watts and weighs out meals, you favor epic all-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 stout aluminum frame with rack and fender mounts, a vibration-absorbing carbon fork, a 2x11 Shimano GRX drivetrain with lower gears for grinding up hills or through rough gravel, hydraulic disc brakes for all-condition stopping power, 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 that keeps the price in check, and a wealth of features like extra tire clearance and customization options so you can confidently take on bigger, better adventures.

Sizing & Tech
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 retailer.
