The Checkpoint ALR 5 is a high-value alloy gravel bike that's kitted out with quality parts for long, rugged, miles on anything from chunky gravel to smooth road surfaces.

It's right for you if...
You favour epic gravel adventures that end with a big beverage 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 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.

Why you'll love it
Its progressive geometry is quick and nimble yet keeps you stable and in control on fast, choppy descents
You get serious versatility that's suited for a wide variety of ride styles, from gravel and bikepacking to daily commutes
Massive tyre clearance means you can use tyres up to 45 c for extra traction and stability in any conditions
Integrated frame bag mounts and rack and mudguard mounts make it easy to carry gear and water
SRAM's Apex 1x12 drivetrain gives you tons of gears for grinding up steep grades.
