Tubeless Tires Out Of The Box

All Checkpoint ALR, SL and SLR models are tubeless and ready to go out of the box. Sealant, valves, and rim strips 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.
