2021 Trek | Checkpoint AL4

Checkpoint ALR 4 is an aluminum gravel bike that offers an incredible amount of capability for the price.

It's right for you if...

You want a single durable, ultra-versatile gravel bike that's ready for adventure. Gravel? Check. Pavement? Check. Multi-day bikepacking? Check. Foul-weather commuting? Check. Check. Check.

The tech you get

A stout aluminum frame with rack and fender mounts, a vibration-absorbing carbon fork, a 2x10 Shimano GRX drivetrain with lower gears for grinding up hills or through rough gravel, hydraulic disc brakes for all-condition stopping power, and wide 700x40c gravel tires for added stability and traction.

The final word

Bring it on, gravel! Checkpoint ALR 4 is a high-value gateway to a world of adventure. It's rugged, fast, comfortable, and has an amazing amount of tech for its price. Though it's made to stand up to the rigors of gravel roads, the frame geometry and accessory mounts make it a great choice for road rides and commutes, too.
