Checkpoint ALR 3 is the best value gravel bike in the lineup. Kitted out with a 300 Series Alpha Aluminum frame, 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 groupset and mechanical disc brakes balance budget with reliability.

• The durable and capable 300 Series Alpha Aluminum frame makes for a fun, stable, and responsive ride
• You get serious versatility thats suited for a wide variety of ride styles, from gravel and bikepacking to daily commutes
• Massive tire clearance means you can use tires up to 45c for extra traction and stability in any conditions
• Fork, top tube, and integrated frame mounts make it easy to carry gear and water
• Powerful mechanical disc brakes make stopping in all conditions easy

New progressive geometry

For quick, nimble handling that still keeps you stable and in control on rougher descents.

Tire clearance

Lots of clearance means you can run meatier tires (700x45mm or 27.5×2.1″) for tackling chunkier gravel and terrain.

Tons of mounts

Integrated frame bag and fender mounts make it easy to carry gear and water.

Dont forget your pedals

This bike doesnt come with pedals because youll have a better time on your new bike if you choose your own. See the pedal guide to find the best pedals for your riding style.
