Protect yourself from flats with Bontrager Thorn Resistant tubes. The asymmetric design uses thicker rubber on the tread side and thinner rubber elsewhere, which saves weight while maximising puncture protection.
- 4.1mm thickness (tread side)
- Asymmetric extrusion puts extra rubber along tyre sidewall and tread zones
