Introducing our premium set of 2 Pcs 20′ Self Sealing Bike Tubes, specifically designed for bicycle enthusiasts looking for an effective solution to prevent flat tires. These tubes come in sizes compatible with 20×3.0, 20×3.1, 20×3.2, 20×3.3, 20×3.4, and 20×3.5 bicycle tires, making them perfect for both road and mountain bikes. The self-sealing technology ensures that any small punctures or cracks are repaired automatically, providing you with a hassle-free riding experience.

The YunSCM brand guarantees quality and reliability. Each inner tube is pre-installed with a sealant that offers maximum puncture protection. This thicker design enhances durability compared to standard inner tubes. What’s more, the self-repairing mechanism efficiently fills any punctured area within a mere 5 to 8 seconds, allowing you to get back on your bike quickly.

Our self-sealing inner tubes are engineered for use in various temperature environments, including colder conditions down to -15°C. This feature ensures that whether you’re riding in the heat of summer or the chill of winter, your bike remains road-ready. It’s important to note that when inflating the tube, avoid focusing the center of gravity or the sealant near the air nozzle to prevent any leakage during the process.

At YunSCM, we strive for excellence in our products. We value your feedback and are constantly seeking to improve our offerings. If you encounter any issues with your bike tubes within the first 180 days, we encourage you to reach out to us.
