This collection brings together all available 20-inch sizes, from the narrowest sections (20x7/8, 20x0.90, 20x1.00…) to extra-wide and fat bike formats (20x4.00, 20x4.50, 20x4.80, 20x5.00).

Each inner tube also corresponds to a precise ETRTO size, making compatibility straightforward: 23-451, 28-406, 37-451, 44-406, 50-406, 57-406, 60-406, 82-406, 100-406, 120-406, and more. This allows you to choose with confidence based on the markings printed on your tyre sidewall.
How to choose the right 20-inch inner tube
To ensure perfect compatibility, always check:
- The tyre size in inches (e.g. 20x1.75, 20x2.125)
- The ETRTO size, printed on the tyre sidewall (e.g. 47-406, 54-406)
- The valve type: Presta (FV), Schrader (AV) or Dunlop (DV)
An inner tube typically covers a range of widths. For example, a 20x1.75–2.125 tube will suit many tyres between 47-406 and 57-406.
