Checkpoint ALR 4 is an aluminium gravel bike that offers an incredible amount of capability for the price. It's built for the rigours of gravel and dirt roads, but it's also right at home on morning commutes and centuries. This bike knows no boundaries, which makes it the ideal gateway to adventure on any road or path.

It's right for you if...

You want a single durable, ultra-versatile gravel bike that's ready for adventure. Gravel? Check. Tarmac? Check. Multi-day bikepacking? Check. Foul-weather commuting? Check. Check. Check.

The tech you get

A stout aluminium frame with rack and mudguard mounts, a vibration-absorbing carbon fork, a 2x10 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:

Bring it on, gravel! Checkpoint ALR 4 is a high-value gateway to a world of adventure. It's rugged, fast, comfortable and has an amazing amount of tech for its price. Though it's made to stand up to the rigours of gravel roads, the frame geometry and accessory mounts make it a great choice for road rides and commutes too.
