It's right for you if...

Unlike the pure roadie who measures watts and weighs out meals, you favour 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 money, including quality, versatility, durability and a ridiculous amount of fun.

The tech you get

A stout aluminium frame with rack and mudguard mounts, a vibration-absorbing carbon fork, a 2x11 Shimano GRX drive train with lower gears for grinding up hills or through rough gravel, hydraulic disc brakes for all-condition stopping power 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 that keeps the price in check, and a wealth of features like extra tyre clearance and customisation options so you can confidently take on bigger, better adventures.
