Description

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 Various Sizes: 26x1.75-2.3; 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 suitable before you buy), width between 1.75-2.3 tire. Standard 35mm schrader valve and 48mm presta valve suitable for most mtb 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 Design: The exquisite carton contains four inner tubes for easy replacement and storage Please note: All inner tubes need to be put into the outer tire before inflating, so that the outer tire will protect the inner tire from exploding. is committed to becoming a good partner for all bicycle owners and enthusiasts
