A stout 300 Series Alpha 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 1x12 SRAM Apex drivetrain 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, the Checkpoint ALR 5 is your ride. 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.
