Butyl Rubber: 14 x 2.125 inner tube is made of butyl rubber, which has airtightness, elastic damping, anti-aging performance, and high heat resistance.Furthermore, compared to ordinary rubber, butyl rubber has a longer service life.

20% Thicker：Compared to ordinary inner tubes, MOLIBISTY inner tubes are 20% thicker, which better absorbs shocks caused by bumps, providing a comfortable riding experience and excellent handling performance.

Excellent Shock Absorption and Airtightness:The 14×2.125 inner tube ensures airtightness and shock absorption, with 8 times better air retention than natural rubber. The sealing system consists of a 90° valve stem and a valve core cap. The black sliding valve core cap creates a unique sealing environment, preventing air leaks from the inner tube.

Tips:Before installation, please clean the inside of the outer tire to remove any sand, pebbles, or sharp debris that could puncture the inner tube. Check the valve position to ensure correct alignment during installation.
