How to choose your inner tube
Check the information indicated on the sidewall of the tyre (diameter and width). For example, 700 x 35 means your tyre is 700mm in diameter and 35mm wide. On the sidewall you will also find the dimensions in mm in international ETRTO. For example: 35-622 means your tyre is 35mm wide with an inner diameter of 700mm (so 700 x 35)
Removing an inner tube
Remove the old inner tube using the B'Twin tyre tools (item code 8047839).
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.
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 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.
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 and puncture it.
Inflating the 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.
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.

Bought these for a CX Sportive (I didn’t want any punctures).
Easy to fit but make your wheels quite heavy.
One of the tubes after inflation sealed its valve, so I cant pump it up anymore. But it doesn’t seem to have lost any pressure (so I guess less of a problem than I first thought). Bought a spare tube to replace that one when it eventually deflates.
