Product Description

PRINCIPLE

During riding, when the inner tube is punctured, the self-replenishing fluid in the inner tube is ejected from the punctured hole at the pressure of the outer air. The self-replenishing fluid condenses rapidly at the puncture hole, blocking the puncture hole, thereby preventing the tire burst phenomenon in the riding process.

We hope to do better in terms of tire quality in order to provide you with better service and satisfactory products; If you have any questions about product quality within a year, you can contact us; You need to provide relevant pictures and information so that we can respond quickly and save you valuable time
Heavy Duty inner tube:20″x3.5″/4.0″ AV32mm (89/102-406) Heavy duty bicycle replacement inner tube, these inner tubes are ideal for a wide range of applications.
