Flat less. Ride more.

Protect yourself from flats with Bontrager Thorn Resistant tubes. Asymmetric design uses thicker rubber on the tread side and thinner rubber elsewhere, which saves weight while maximizing puncture protection.

  • Asymmetric extrusion puts extra rubber along tire sidewall and tread zones
  • 100% inspected for guaranteed quality
