DURO (1 PAIR) BICYCLE Inner Tube 26" x 1-3/8" SCHRADER 33mm Long VALVE.

Description: SpecificationsSize: 26 x 1 3/8This tube fits 26-inch wheels with a 1 3/8-inch width, which is narrower than the typical 26-inch mountain or hybrid bike tires. The corresponding ISO size for these tires is 37-590. The 590mm diameter is specific to 26 x 1 3/8 tires and does not fit the more common 559mm 26-inch mountain bike rims.Valve Specifications Valve Type: Schrader ValveThis is the standard valve type used on most modern bicycles, especially commuter, hybrid, and older vintage bikes, as well as some road bikes. Valve Length: 33mmThe 33mm valve length is designed to work with most standard 26-inch rims, providing adequate valve height for easy inflation without extending too far. Valve Core: RemovableThe Schrader valve includes a removable core, allowing for easy sealing with sealant, or valve core replacement in case of damage. This feature also supports adding sealant for puncture protection. Valve Stem: SmoothA smooth valve stem reduces friction against the rim and makes insertion into the valve hole easier. Additionally, it prevents excessive wear on the tube and valve stem interface, ensuring a better seal and longevity. Valve Angle: 0 degrees (Straight)The valve stem is oriented at a 0-degree angle (straight), standard for most bicycle rims. This straightforward alignment makes inflation convenient.Material & DurabilityMaterial: Butyl RubberDuro uses durable butyl rubber for its tubes, known for its puncture resistance and excellent air retention. Butyl is commonly used for tubes because it maintains inflation longer and provides reliable protection against cuts.Compatibility Intended Tire Size: 26 x 1 3/8This tube is suitable only for bikes with 26 x 1 3/8 inch tires, which are generally seen on vintage and classic bikes, some commuter bikes, and older road bicycles. The tube's ISO size (590mm) matches specific rims designed for this 26 x 1 3/8 standard. Recommended Uses:Vintage Road Bikes: Many older road bikes, especially those from the mid-20th century, use this unique size for its narrower width, which aids in smooth pavement riding.City and Commuter Bikes: Some commuter or city bikes also use this narrower profile, as it provides a balance between weight and performance on paved roads.Classic and Heritage Bicycles: If you have a classic bike, especially European brands like Raleigh, this tube size may be the exact match for the traditional narrow 26-inch wheels often found on these models.BrandBrand: DuroKnown for reliability, Duro provides a wide range of tubes for various cycling needs. This tube is designed for cyclists who prefer or require the vintage 26 x 1 3/8 size, ensuring high quality, durability, and ease of installation.
