The Lizusidtsy ultralight bike inner tube is designed specifically for road bicycles with tire sizes ranging from 700x18C to 700x32C. This inner tube combines lightweight construction with robust performance, making it an ideal choice for cyclists who prioritize speed and efficiency on their rides.

One of the standout features of this inner tube is its material. Constructed from high-quality TPU (thermoplastic polyurethane), it offers excellent toughness while remaining incredibly light. This means you can enjoy a faster ride without the added weight of a traditional inner tube. The orange color adds a vibrant touch, ensuring that it stands out in your bike setup.

When considering tire pressure, it is essential to be aware of the effects of temperature. As temperatures rise, particularly when riding on high-temperature black asphalt pavement exceeding 65°C (150°F), the tire pressure can increase significantly. In fact, for every 3° (5°F) increase in temperature, the tire pressure may rise by about 1%. This means that if you inflate your tires in a cool environment (around 18°C / 65°F) and then ride in hotter conditions (up to 35°C / 95°F), you could see an increase in the inner tube pressure of approximately 0.5 bar (8 PSI).

It is crucial to manage tire pressure properly to avoid potential accidents. Too high tire pressure can lead to the tire breaking away from the rim while cycling, increasing the risk of injury. Therefore, if pneumatic tires are stored in high temperatures (over 60°C / 140°F), such as in a car on a hot day, we recommend deflating the inner tube to about 1 bar (15 PSI) to prevent valve deformation.

This product is sold as a single unit, with the package containing one super light bicycle inner tube. Please note that due to lighting conditions and different display settings, the color of the actual item may vary slightly from the images shown. Additionally, a measurement error within +/- 1-3cm is acceptable for this product.

In summary, the Lizusidtsy ultralight bike inner tube is a smart investment for any cyclist looking to enhance their riding experience. With its lightweight design, durable TPU material, and attention to tire pressure management, you can ride with confidence and enjoy a smoother, safer journey.
