26 Heavy Duty Bike Tubes for 26x1.75/2.25 Tires with Schrader Valve

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

The 26"x1.75"/2.25" AV32MM(45/57-559) heavy-duty bicycle replacement inner tube is an ideal option for a wide range of applications. These heavy-duty inner tubes enhance the ductility of the heavy load tire, expanding the scope of application. They are compatible with 26x1.75, 26x1.90, 26x1.95, 26x2.0, 26x2.10, 26x2.125, 26x2.25 tires.

The Self Sealing Bike Inner Tube is a self-repair solution for small holes or very fine cracks. For instance, after a long time, some places may start leaking air quietly, or accidentally hitting nails and other problems can be easily repaired. It is worth noting that this self-repairing inner tube can be used within the normal temperature environment and even on cold days down to -15°C, making it more conducive to travel in cold weather.

The pre-installed sealant provides maximum puncture protection and prevents flat tires on your bike, ensuring a safer ride. The thicker design of the self-repairing inner tube makes it more durable than the normal inner tube. The bicycle inner tube rolls through the tire repair liquid to automatically fill the punctured area, with the leak being repaired within 5~8 seconds under normal conditions.

The heavy, strong, and highly durable butyl rubber used in these inner tubes serves as an excellent shock absorber, reducing vibration and eliminating the shock caused by bumps and rough surfaces on the road or pavement. This heavy-duty butyl rubber ensures maximum ride comfort, upgrading your riding experience.

Made of high-quality butyl rubber composite material, these inner tubes exhibit good air tightness, heat resistance, and durability. Every product undergoes rigorous screening before delivery to ensure quality.

The thickened inner tube has a higher content of butyl rubber, with the weight being 285g compared to the 230.5g of the conventional inner tube, a 24% increase in weight. This thicker and more airtight design offers enhanced performance.

To prevent the self-sealing fluid from flowing out during operation, it is crucial to avoid concentrating the center of gravity or the liquid near the air nozzle when pumping up the tire.

The 26"x1.75"/2.25" bicycle heavy-duty replacement inner tube is easy to install and remove. It is essential to check the valve position to ensure the correct installation direction.

Before installing the inner tube, it is recommended to immerse it in water for inspection. If there are bubbles, it indicates damage, and you can contact the manufacturer. Again, check the valve position to ensure the correct installation direction. Avoid puncturing the inflatable inner tube by sharp objects.

The manufacturer offers a 100% product quality assurance. If there is any problem with the product within 1 year, you can get in touch with them, providing evidence pictures and relevant situation descriptions, and they will respond quickly to address your concerns and provide satisfactory solutions. The goal is to continuously improve the tires and provide better service and more satisfactory products based on customer feedback and suggestions.
