Product details

Standard bicycle tube with a 32 mm Dunlop valve. Thanks to high-quality materials and uniform wall thickness, the tube retains air for an above-average duration. The tube is made of 100% recyclable rubber and is suitable for various tire sizes. It weighs approximately 130 grams.

The bicycle tube is suitable for the following tire sizes:

  • 28-540 | 24 x 1 1/8
  • 28-541 | 600 x 28A
  • 30-540 | 24 x 1.20
  • 32-540 | 24 x 1 3/8 x 1 1/4
  • 32-541 | 24 x 1 3/8 x 1 1/4 | 600 x 32A
  • 37-540 | 24 x 1 3/8
  • 37-541 | 600 x 35A
  • 37-541 | 600 x 37A
  • 40-507 | 24 x 1.50
  • 40-540 | 24 x 1 3/8 x 1 1/2
  • 44-507 | 24 x 1.625
  • 44-507 | 24 x 1.75
  • 47-507 | 24 x 1.75
  • 47-507 | 24 x 1.85
  • 47-507 | 24 x 1.90

The sizes mentioned above are ETRTO, inch, and French sizes.

The ETRTO measurement consists of two numbers, for example, 28-540. The first number 28 is the width of the tire in millimeters. The second number 540 indicates the inner diameter of the bicycle tire in millimeters.

The inch size consists of 2 or 3 numbers. The first number is the diameter of the tire in inches. The second number is the height of the tire, and the third number is the width of the tire. The German measurement system also uses inches, but there the second number is the width and the third is the height.

The French size consists of two numbers plus a letter, for example: 600 x 28A. The number 600 indicates the outer diameter in millimeters. The second number 28 indicates the tire width in millimeters. The letter (A) stands for the rim size. The tire size is often indicated on the sidewall of the tire itself.
