Introducing the DBXIIART Premium Quality Bike Tubes, a must-have for any cycling enthusiast. This 4-pack of heavy-duty inner tubes is designed to fit a wide range of bicycles, including road bikes, gravel bikes, and mountain bikes. The sizes included in this pack are 700x38C, 700x40C, 700x42C, 700x43C, and 700x45C, ensuring compatibility with most standard bicycle wheels.

Each inner tube is crafted from high-quality butyl rubber, known for its superior airtight properties. In fact, butyl rubber is 8 times more airtight than natural rubber, making it less prone to rupture even when exposed to varying temperature conditions. This means you can ride with confidence, knowing that your tires are less likely to fail.

When it comes to quality and reliability, the DBXIIART bike tubes stand out. The wall thickness of these tubes is 1.1mm, which is significantly thicker than many other brands. This added thickness contributes to higher air tightness and the ability to withstand greater pressure, making these tubes perfect for high-strength impacts.

Another fantastic feature of these tubes is their excellent sealing performance and anti-aging properties. The butyl rubber material not only absorbs shocks from bumpy roads, but it also enhances the overall comfort and safety of your ride. You can trust that these tubes will perform well under a variety of conditions.

Installation is a breeze with our bike inner tubes. They fit 700c, 29′, and 27.5′ wheels. Before purchasing, please confirm that your bicycle tires are compatible. The standard 35mm Schrader valve is suitable for most standard rims, making installation quick and easy. Following the inflation guide will ensure that you pump your tires correctly for optimal performance.

To enhance your cycling experience even further, this package includes two strong nylon tire levers. Unlike ordinary plastic levers, these nylon levers are sturdy and resistant to breaking, providing you with the tools you need for efficient tire changes.
