Description

Checkpoint ALR 3 is the best value gravel bike in the line-up. Kitted out with a 300 Series Alpha Aluminium frame, the Checkpoint ALR 3 is just as responsive on chunky gravel roads as it is smooth on the tarmac. Tubeless-ready wheels help fight punctures in the rough while a 2×9-speed Shimano group set and mechanical disc brakes balance budget with reliability.

The tech you get

A responsive 300 Series Alpha Aluminium frame, hidden cables that won’t interfere with bags, integrated rack, mudguard and frame bag mounts, a 2×9 Shimano Sora drivetrain for smooth shifting on punchy climbs and variable terrain, mechanical disc brakes for ease of stopping quick in all conditions, tubeless-ready rims and wide Bontrager Girona Pro 700x42c gravel tyres for added comfort and traction.

The final word

When you want to start exploring the road less travelled, reach for the Checkpoint ALR 3. This budget-minded gravel bike gives you room to grow from rugged commutes to gravel grinds with economical components and a comfortable, capable frame that’s built to take you on every adventure.
