YunSCM 2-Pack 26x4.0 Inner Tubes, Thick Wall, 32mm Schrader Valve, 26x3.5/4.0 Bicycle Tubes, Suitable for 26x3.5/26x4.0 Mountain Bikes and Fat Bikes

[26"x3.5-4.0 Bicycle Tube]: Suitable for 26x3.5/4.0 bicycles, with a 32mm Schrader valve. Suitable for most electric and fat bikes. The tube's air intake is the same as that of motorcycles and cars, making it easy to inflate. You can now use the same air pressure gauge you use in your car, making tire pressure management much easier. Note: Please check your tire size before purchasing. Tire size is usually displayed on the side of the outer tire. [Space-saving and easy to carry]: The 26x4.0 bicycle tube takes up very little space when folded, making it easy to carry when riding long distances, avoiding the embarrassment of being unable to ride after a puncture. [High-quality butyl rubber]: This 26/4.0 material provides better airtightness and holds air for a longer period of time, eliminating the need to constantly inflate. [New release] [Thickness Design]: To meet the needs of frequent riders and further enhance the durability of our tubes, we developed a thicker, reinforced tube that is approximately 25% thicker than our standard tubes, with a thickness that is visible to the naked eye. This improves the tube's explosion resistance and puncture resistance. [Budget Saving]: Doing it yourself saves money compared to going to a local shop to replace your tube. As a spare tube, it can prevent the embarrassment of being unable to ride after a tube bursts.
