Butyl Rubber: Butyl rubber is currently the mainstream material for bicycle inner tubes on the market, favored for its excellent airtightness, wear resistance, and aging resistance. It maintains stable performance in various harsh environments, ensuring the inner tube's durability.
Natural Rubber: Natural rubber, another common inner tube material, has high elasticity and flexibility. It has good shock absorption properties, effectively reducing bumps during riding and improving riding comfort. However, natural rubber has relatively weaker wear resistance and aging resistance, requiring regular replacement.
