With Checkpoint ALR 5, you're getting high-quality parts at exceptional value, which means you'll have extra dough for adventure travel… and burritos.
This bike is exceedingly versatile and suited to a wide variety of riding styles, including gravel rides, bikepacking and daily commutes.
Massive tyre clearance means you can use tyres up to 45 c for extra traction and stability in any conditions.
