Precision-engineered for 20x4.0 fat-tire bikes, our inner tube solves the rider frustration: trailside flats. We use 1.0mm reinforced butyl rubber – 40% thicker than standard tubes (0.6mm) – proven to resist glass, thorns, and curb impacts across 5,000+ urban and off-road test miles. The heavy-duty brass valve endures 300+ high-pressure inflations without failure.
Forget flimsy alternatives. We use high-elasticity butyl compound that retains air 68% longer than natural rubber blends. The result? Consistent pressure during freezing descents or scorching desert rides. Thicker sidewalls shield against rim cuts, while the seamless mold reduces failure points. Durability isn't accidental-it's engineered.

Precautions for use
1.Avoid excessive stretching of the inner tube
The inner tube should be evenly embedded in the outer tube to avoid local excessive stretching (especially near the valve).
Excessive stretching may cause the inner tube to become thinner and increase the risk of tire blowout.
2.Tips for installing the valve
The valve should be aligned with the valve hole of the rim to avoid skewness and leakage.
Apply a small amount of grease (such as special butter) to the base of the valve to reduce friction damage.
