Introducing the 2 Pcs 700C TPU Ultralight Tire Tubes, specifically designed for bicycle enthusiasts who value performance and environmental sustainability. These inner tubes are engineered to fit perfectly in 700x23C, 700x25C, and 700x28C bike tires, making them a versatile choice for various cycling experiences.

Crafted with a FV60mm Presta valve, these tubes are not only compatible with a wide range of tire sizes (ETRTO: 23-622, 24-622, 25-622, 26-622, 27-622, 28-622) but also feature a cutting-edge TPU (thermoplastic polyurethane elastomer) construction. This innovative material stands out as an environmentally friendly option, being 100% recyclable. By choosing TPU, you contribute to a greener planet while enjoying cycling.

One of the standout features of these TPU inner tubes is their lightweight design. They are significantly lighter than traditional butyl rubber tubes, offering a weight reduction of up to 70%. This reduction in rotational mass enhances your cycling experience, making your rides more agile and responsive. You will notice improved handling and climbing speed, allowing for a more enjoyable ride.

Portability is another key advantage of our TPU inner tubes. When folded, they are over 50% smaller than conventional inner tubes, making them easy to carry. This compact design frees up space in your pocket or cycling bag, allowing you to carry essential supplies without the bulk.

Moreover, the TPU material is compatible with environmentally friendly outer tubes and colored tires, ensuring that it will not affect their appearance. This means you can enjoy both performance and aesthetics without compromise.

These ultra-lightweight inner tubes are ideal for short and easy rides, helping you conserve energy. Whether you’re commuting or enjoying a leisurely ride, the TPU inner tubes will save you physical strength. However, it is crucial to regularly check the tire pressure and replenish air as needed for optimal performance.

Installation and maintenance of these inner tubes require some special attention. Due to their ultra-thin nature (only 0.2-0.3mm thick), it is essential to keep your tire tread and frame clean and flat to avoid damage. Additionally, we advise against inflating the TPU inner tube without proper assembly between the outer tire and rim, as excessive air pressure can lead to irreversible damage.

High temperatures can pose a risk to TPU materials. In rare instances, rim brakes may overheat, leading to potential safety issues. Consequently, we recommend using these TPU inner tubes exclusively on bicycles equipped with disc brakes for maximum safety.
