Product feature
  1. How to choose your inner tube
    Write down all visible information from the tyre sidewall (diameter and width). For example, 700 x 23 means your tyre is 700 mm in diameter and 23 mm wide. You will also find the dimensions in mm in the international ETRTO measurements. For example: 23-622 means the tyre is 23 mm wide with an inner diameter of 700 mm (approx. 700 x 23 mm)
  2. Removing an inner tube
    Remove the old inner tube using B'Twin tyre levers (ref 8047839)
  3. What to check before installing your new 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 the 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. Fitting your 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 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 from the opposite side of the valve Finish at the top of the valve to avoid pinching Never use a screwdriver or tyre lever to mount the tyre or you could pinch the inner tube, puncturing it.
  6. Inflating the tyre
    Inflate your tyre carefully, to the pressure recommended by the manufacturer (check the sidewall, written in PSI or in bars: 1 bar = 14.51 PSI) Regularly check that the tyre is in the right position while inflating.
  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.
