The RUTU 20×2.125/2.40 Inner Tube is designed to cater to a wide range of bicycle models, ensuring that you have the reliability and performance you need for your rides. With a size of 20’x2.125/2.40′, it fits perfectly on 20-inch wheels and is compatible with tire widths ranging from 2.125 to 2.40 inches. This makes it suitable for various bicycles, including Road Bikes, Track Bikes, Cyclocross Bikes, Mountain Bikes, Cruiser Bikes, Fat Bikes, BMX Bikes, and more.

Constructed from high-quality butyl rubber, these inner tubes offer superior resistance to aging and high temperatures when compared to natural rubber alternatives. This durability translates into a service life of up to 5 years, which is double that of standard inner tubes. Additionally, the excellent air tightness of butyl rubber means that once inflated, the inner tube can maintain its pressure for 5 to 6 months, significantly reducing the frequency of re-inflation that is often required with ordinary rubber tubes, which typically need attention every 1 to 2 months.

One of the standout features of our inner tube is its heavy-duty construction. It is thicker than typical inner tubes, which contributes to a smoother and more comfortable ride. This thickness not only helps in absorbing bumps and shocks from the road but also enhances the overall durability and tear resistance of the tube, providing peace of mind during your cycling adventures.

To ensure you can maintain the best air tightness over time, our package includes not only the high-quality inner tubes but also additional valve cores and dust caps. The valve core wrench provided makes it easy to replace the valve cores quickly and efficiently, ensuring long-term performance. The aluminum dust-proof caps are designed for high strength and scratch resistance, effectively preventing dust and debris from entering the valve tube, which could compromise its performance.

In summary, the RUTU 20×2.125/2.40 Inner Tube is an excellent choice for cyclists looking for durability, reliability, and performance. Whether you’re navigating city streets or exploring rugged trails, these inner tubes will provide the support and comfort you need for an enjoyable ride. Equip your bike with our heavy-duty inner tubes and experience the difference on your next cycling journey.
