Natural Rubber
Natural rubber is a traditional material for bicycle inner tubes. It possesses good elasticity and abrasion resistance, providing a comfortable riding experience. However, natural rubber also has some drawbacks, such as being prone to aging and not heat-resistant. Therefore, when choosing natural rubber inner tubes, it's important to consider their lifespan and maintenance methods.
Butyl Rubber
Butyl rubber is a synthetic rubber with excellent airtightness and chemical stability, maintaining good performance over a wide temperature range. Due to these advantages, butyl rubber inner tubes are widely used in the bicycle industry. However, butyl rubber has relatively poor elasticity, which may affect riding comfort.
Polyurethane Rubber
Polyurethane rubber is a high-performance synthetic rubber that combines the advantages of natural rubber and butyl rubber, possessing excellent elasticity, abrasion resistance, and airtightness. Therefore, polyurethane rubber inner tubes are widely used in high-end bicycles. However, polyurethane rubber has a higher cost, resulting in a relatively higher price.
