Details

Checkpoint ALR 4 is the best value gravel bike in the lineup. It's a high-quality build that will hold up for long, rugged miles on pavement, dirt, and even the most treacherous gravel roads.

The ALR 4 is also more than just a gravel bike! Its capable of tackling century rides and the daily commute. Checkpoint ALR 4 is your ticket to turning every ride into an adventure.

The Checkpoint ALR 4 features a sturdy 300 Series Alpha Aluminum frame, a SRAM Apex 1X11 speed drivetrain for simplicity when shifting gears on rough gravel roads and plenty of low gearing for steep climbs. It also features disc brakes for all-condition stopping power, tubeless ready rims, and wide 700x40c gravel tires for added stability and traction.

Checkpoint ALR 4 is the perfect ride for ease of entry into the wide world of gravel.

All Checkpoint ALR, SL and SLR come set up with 700x40c tubeless tires. Valves, sealant, and rim strip included.

Want a carbon frame and a performance-level drivetrain on your bike? Check out the Trek Checkpoint SL 5, with an upgraded drivetrains and a 500 series OCLV carbon frame.

Due to supply-chain issues, Specs are subject to change without notice.

1x11 SRAM APEX drivetrain with lower gears (40T chainring paired with an 11-42 tooth cassette) helps you grind up hills or through rough gravel.

Lots of clearance means you can run meatier tires (700x45mm or 27.5x2.1") for tackling chunkier gravel and terrain.

All Trek Checkpoint ALR, SL and SLR models come tubeless out of the box. Sealant, valves, and rim stips included.

Ditching the tubes and going tubeless will help you get the most performance out of your tires. There are no tubes to pinch, so you can run lower pressures for better traction, and you get more control and a smoother, faster ride. As an added bonus, a tubeless setup can help seal punctures before they become flats.

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