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. Our sidewall thickness is thicker, the allowable inflatable section is more elastic and resistant to puncture Suitable for Most Inner Tubes: 6 packs, 700X18/25C F/V-48 fits 700c road bikes that are between 18 to 25 wide – 48mm Presta Valve; 700x25/32C F/V-60( 25 to 32 wide – 60 mm Presta Valve); 700X35/45C F/V -48 (35 to 45 wide – 48mm Presta Valve) 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 Easy to Install: Simple and quick installation process. Easy 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 Outstanding Inner Tube: If you have any questions or dislike our road bike inner tube for any reason, please do not hesitate to contact us.
