A properly set up tubeless system lets you run lower tire pressure for better traction, added confidence, and a smoother, faster ride.
Bontrager offers a complete tubeless system including wheels, tires, sealant, valves, and rim strips. Every part of this setup is designed to work smoothly together, for the best in performance and ease of use.
Going tubeless adds performance, speed, and comfort to your ride and can even help seal punctures before they become flats. Bontrager makes tubeless setup simple, and we'll teach you everything you need to know to do it yourself.
