Bicycle stab-proof inner tube

Features: Strong explosion-proof, light weight, TPE environmental protection material Weight: 90-60g Anti-puncture performance: After being pierced by a nail, it will not leak air quickly. If the nail is not quickly removed, you can continue to ride for a while. If it is pulled out, the micro-holes are also leaking. Just repair the tire in time. Explosion-proof performance: The inner tube will not burst if it is blown through by nails or locally impacted, as long as the tire patch is applied. Convenient.
