Product Information

The TUBE 29 x 2.125 – 2.5 A/V 48mm is a bicycle inner tube designed for tires with a diameter of 29 inches and a width ranging from 2.125 inches to 2.5 inches. Here’s a breakdown of its key features:

  • Size Compatibility:
    • Diameter: 29 inches – Fits wheels with a diameter of 29 inches.
    • Width: 2.125 – 2.5 inches – Compatible with tires ranging from 2.125 inches to 2.5 inches in width.
  • Valve Type: A/V valve (also known as Schrader valve) – This is the most common type of valve used on bicycle inner tubes. It has a wider base and uses a pin to inflate.
  • Valve Stem Length: 48mm – This is a standard length valve stem that should be compatible with most 29-inch rims. However, it’s always a good practice to double-check your rim’s valve hole size to ensure the stem will fit through.
  • Material: Likely butyl rubber – Butyl rubber is the most common material used for inner tubes because it is air-tight and relatively durable.

Potential Uses:

  • Mountain bikes: This size is commonly used in mountain bike tires, especially those for trail riding or all-mountain riding.
  • E-bikes: Some e-bikes with 29-inch wheels might use inner tubes of this size.
  • Gravel bikes: Some gravel bikes with 29-inch wheels might also use this inner tube size.

Here are some additional things to consider when purchasing a TUBE 29 x 2.125 – 2.5 A/V 48mm inner tube:

  • Existing tire size: Double-check the size of your bicycle tire to ensure this inner tube is compatible. The tire size is usually printed on the sidewall of the tire.
  • Puncture resistance: If you experience frequent flats, consider puncture-resistant inner tubes that offer an extra layer of protection. Some manufacturers may offer this option within the same size range.
