Product feature
  1. How to choose an inner tube:
    Check all the information indicated on the sidewall of the tyre (diameter and width). For example, 14 x 1.90 means your tyre is 14 inches in diameter and 1.90 inches wide. On the tyre sidewall you will also find the dimensions in mm in ETRTO international units. For example, 47-254 means a tyre that is 47mm wide and has an inner diameter of 254mm (approx. 14 x 1.90).
  2. Removing an inner tube:
    Remove the old inner tube using B'Twin tyre levers
  3. Checks to carry out before installing an inner tube:
    Check the condition of your tyre and replace it if necessary. Make sure no objects are lodged in the tyre. Check the condition of your tyre rim strip. A rim strip that is even slightly bent can cause punctures. Check that your rim does not have any other issues that could damage your inner tube.
  4. Installing an inner tube:
    Watch our video before you start. Pre-inflate the inner tube slightly to avoid pinching. Insert the valve, making sure you are using the correct valve for your rim. Put the inner tube entirely inside the tyre so that it fits inside the rim. Take care not to pinch the inner tube when fitting.
  5. Fitting a tyre:
    Start mounting the tyre at the valve. Finish mounting the tyre opposite the valve to avoid pinching the inner tube. Never mount your tyre with a tool or a tyre lever, as you risk pinching and puncturing the inner tube.
  6. Inflating a tyre:
    Inflate your tyre carefully, to the pressure recommended by the manufacturer (visible on the tyre sidewall in PSI or bars, 1 bar = 14.51 PSI). Regularly check that your tyre is in the correct position as you inflate it.
  7. Pro advice:
    To prevent any puncture from pinching and to achieve the best performance, we recommend checking and, if necessary, pumping up your front tyre before each ride.
  8. Weight:

  9. Complementary products:
