It's right for you if...
Unlike the pure roadie who measures watts and weighs out meals, you favour epic off-road adventures that probably end with a beer and a bag of chips. But that doesn't mean you'll compromise on performance. You expect to get a lot for your hard-earned money, including quality, versatility, durability and a ridiculous amount of fun.
The tech you get
A sturdy aluminium 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 mudguard 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 tyres for added stability and traction.
The final word
If the amount of adventure you can get per pound 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 tyre clearance and customisation 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.
