    Details
    Product feature
    1. How to choose your inner tube
      Check the information indicated on the sidewall of the tyre (diameter and width). For example, 700 x 23 means your tyre is 700mm in diameter and 23mm wide. On the sidewall, you will also find the dimensions in mm in international ETRTO measurements. For example: 23-622 means your tyre is 23mm wide with an inner diameter of 700mm (so 700 x 23).
    2. Removing an inner tube
      Remove the used inner tube using B'Twin tyre levers (item code 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 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. Fitting your 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.

      Awful quality, you get what you pay for here with this product. Inners cannot handle the PSI suggested upon the packaging.
      I went through two sets in one week, back off the valve splits open.
