High-Quality Rubber Material: Different from ordinary inner tubes, we use 60% high butyl rubber. The air tightness of this high-quality rubber is 8 times that of natural rubber, and it is not easy to break due to temperature changes. The conventional sidewall thickness is 0.8~0.95MM, but our sidewall thickness is 1.1~1.2MM, which is thicker than the sidewall on the market and is more puncture resistant
SIZE: 26x1.75/2.3, 29x1.75/2.3 A/V Scharder Valve 35mm or F/V Presta Valve 48mm; 26 means our bike tubes fit 26 wheel (pls kindly confirm that your bike tire is 26 or 29 inch before you buy), width between 1.75-2.3 tire. Standard 35mm schrader valve and 48mm presta valve suitable for most mtb inner tubes
Simple and Quick Installation Process: Each mtb inner tube comes with an extra pry bar, which is convenient for users to replace more easily. Hassle-free to replace your old tire tubes within minutes which is time saving and efficient. It can also be done easily by novices, especially suitable for cycling enthusiasts who are often troubled by changing inner tubes
Vulcanized Tubes: Each of our inner tubes have passed a strict 100% quality control inspection. And all tubes are round cured to ensure uniform roundness and better reliability. After explosion-proof and inflation tests, our quality control can give you 100% peace of mind
