Description

1. Size: 20 x 1.75/1.95/2.125 The 20 x 1.75/1.95/2.125 sizing indicates that this tube is compatible with 20-inch bicycle tires of widths ranging from 1.75 inches to 2.125 inches . This range of tire widths ensures that the tube can fit a variety of tire types, including standard tires commonly found on BMX bikes, cruisers, and children's bicycles. The ability to fit multiple widths makes this tube a flexible choice for bike owners with varying tire specifications. 2. Valve Type: Schrader Valve This tube comes with a Schrader valve , which is the most common valve type found on many bicycles, particularly on kids’ bikes, BMX bikes, and some standard adult bicycles. The Schrader valve is the same type of valve used in car tires, making it widely compatible with most bike pumps and air compressors. This valve type is durable and can withstand higher pressures than the more fragile Presta valve, making it suitable for casual and recreational use. 3. Valve Length: 48mm The 48mm valve length is suitable for rims with a medium profile or standard height . It ensures that the valve stem extends enough for easy access when inflating the tube. A 48mm valve is long enough to allow the use of most pumps, even those with a thicker rim, and ensures that the valve reaches outside of the rim without being too short or too long. It's important to note that this length is versatile for various rim heights, but for rims with an especially deep profile, a longer valve may be needed. 4. Valve Core: Removable The removable valve core allows for easy maintenance and customization. If you need to replace the valve core due to damage or wear, you can do so without replacing the entire inner tube. The removable valve core also makes it easier to add valve extenders for deeper rims or to make adjustments to air pressure by using different cores designed for specific uses. The ability to remove and replace the core provides an additional level of durability and functionality. 5. Valve Stem: Smooth The smooth valve stem refers to the exterior surface of the valve, which is designed for easy insertion and removal from a valve pump or air compressor. The smooth design minimizes friction when inflating or deflating the tire, helping the process go more smoothly. It also contributes to the overall durability of the valve, reducing the chance of it getting clogged with dirt or debris when not in use. 6. Valve Angle: 0° The 0° valve angle means that the valve stem is straight and points directly out from the tube. This is the most common configuration for Schrader valves and is suitable for most standard rims. A straight valve allows for easy access to the pump or air compressor, making it simple to inflate the tire without any additional manipulation of the valve. This is especially useful for everyday cycling needs, where convenience and accessibility are priorities. 7. Brand: Duro Duro is a well-known and reputable brand in the bicycle industry, specializing in manufacturing quality tires and inner tubes. Duro's products are known for their affordability, reliability, and good performance across a wide range of bike types. The brand has a strong presence in the cycling market, offering products for recreational, commuting, and competitive riding. This tube reflects Duro's commitment to providing durable, high-quality bicycle accessories that are designed to meet the needs of everyday cyclists. 8. Material and Durability Material : The tube is made from high-quality rubber that is flexible and durable, designed to withstand typical riding conditions. It offers good resistance to punctures, abrasions, and wear, making it ideal for general use. The rubber construction allows the tube to stretch and adapt to the various tire sizes it can fit (1.75, 1.95, and 2.125 inches wide), while maintaining air retention over time. Durability : The tube's rubber material is durable enough to handle bumps, small punctures, and abrasions during regular cycling. However, like all inner tubes, it’s important to avoid excessive contact with sharp objects and to maintain the proper tire pressure to prolong its life. Using the correct pump pressure will help avoid unnecessary stress on the tube, ensuring it lasts longer. 9. Compatibility This tube is compatible with a variety of 20-inch tires that fall within the specified width range of 1.75 to 2.125 inches. These sizes are commonly found on many bikes, including BMX, cruiser, and children’s bicycles. Its versatility in fitting multiple tire widths makes it a practical choice for bike shops or cyclists who need to stock a tube that covers different sizes of 20-inch tires. 10. Intended Use The Duro 20 x 1.75/1.95/2.125 tube is primarily intended for recreational, urban, and casual riding . It's ideal for everyday cyclists who ride on paved streets, gravel paths, or smooth dirt trails. It’s a versatile inner tube that can be used in a variety of bicycles, including those used for commuting, leisurely rides, or as a replacement tube for bikes with 20-inch tires. It’s not designed for extreme off-road use or high-performance racing but serves well for casual and moderate cycling conditions.
