Checkpoint ALR 5 is the best value gravel bike in the line-up. It's a high-quality build that will hold up for long, rugged miles on roads, dirt and even the most treacherous gravel. 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.

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.
