Tire Clearance

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

Tubeless Tires

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.

Tons of Mounts

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