Description PUNCTURE – RESISTANT PROTECTION: The high elasticity and toughness of TPU material provide extra puncture protection for the inner tube, making your rides more reassuring EXCELLENT AIR TIGHTNESS: There is only one ring of joint around the valve, reducing the possibility of air leakage and ensuring no need for frequent inflation during long rides STRONG COMPATIBILITY: One specification can be compatible with most rim heights, simplifying the complexity of selecting and carrying spare inner tubes INITIAL INFLATION GUIDE: Inflate the inner tube 2 – 3 times when it's empty, but not exceeding 0.5 bar. Exceeding this pressure may cause irreversible expansion PRE – INSTALLATION CHECK: Don't rush to install the inner tube upon receipt. To ensure quality, check it first. Inflate the inner tube and put it in water, then slowly rotate it to check for leaks as shown in the picture below
