Product feature
  1. How to choose an inner tube
    Check the information indicated on the sidewall of the tyre (diameter and width). For example, 26 x 2.20 means a tyre with a 26-inch diameter and 2.2 inches wide. On the tyre sidewall you will also find the dimensions in mm in ETRTO international units. For example, 50-559 means a tyre that is 50 mm wide and has an inner diameter of 559 mm (approx. 26 x 2.00).
  2. Removing an inner tube
    Remove the used inner tube using B'Twin tyre levers (item code 8047839).
  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 the inner tube
    Pre-inflate the inner tube slightly to avoid pinching. Insert the valve, making sure you are using the correct valve for your rims. 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. Mounting the tyre
    Start by mounting the tyre onto the wheel on the opposite side to the valve. Finish mounting the tyre at the valve to avoid pinching the inner tube. Never mount your tyre using a screwdriver or a tyre lever as you risk pinching and puncturing the inner tube.
  6. Inflating the tyre
    Inflate your tyre carefully to the pressure recommended by the manufacturer (visible on the sidewall of the tyre in PSI or bars; 1 bars = 14.51 PSI). Regularly check that your tyre is in the correct position as you inflate it.
  7. Tip from the pros
    To avoid punctures from pinching and for best tyre performance, we recommend that you check your tyres and inflate them to the suggested pressure before every ride.
