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.

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.

- This bike is exceedingly versatile and suited to a wide variety of riding styles, including gravel rides, bikepacking and daily commutes
- Mounts on the seat tube and both sides of the down tube make it easy to carry extra gear and water
