Continental 42mm Presta Valve Tube, Black, 700 x 25C-32C, Race 28-(700C)-Wide
- 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.
- 29 means our bike tubes fit 29 wheel (pls kindly confirm that your bike tire is suitable before you buy), width between 1.75-2.3 tire. Standard 35mm schrader 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 two inner tubes for easy replacement and storage. There are no other products of inferior quality as gifts, and all the costs are spent on the products you actually buy.
- Outstanding Inner Tube & Worry-free Purchase: If you have any questions or dislike our mountain bike inner tube for any reason, please do....
