TECHNICAL INFORMATIONS

How to choose an inner tube

Check the sidewall for tire information (diameter and width).
For example, 20 x 2.10 means your tire is 20" in diameter and 2.10" wide.
The dimensions in mm (ETRTO international unit) are also on the tire sidewall. For example, 50-406 means that the tire is 50-mm wide with a 406 mm inner diameter (approx. 20 x 2.00).

Removing an inner tube

Remove the old inner tube using Btwin tire levers.

Checks to carry out before installing an inner tube

Check the condition of your tire and replace it if necessary.
Make sure no objects are lodged in the tire.
Check the condition of your tire rim strip. A rim strip that’s even slightly bent can cause punctures.
Check that your rim doesn’t have any other issues that could damage your inner tube.

Installing the inner tube

Watch our video before you start.
Pre-inflate the inner tube slightly to avoid pinching.
Make sure you’re using the correct valve for your rim and then insert it.
Put the entire inner tube inside the tire so that it fits inside the rim.
Take care not to pinch the inner tube when installing it.

Installing the tire

Start installing the tire at the valve.
Finish installing the tire across from the valve to avoid pinching the inner tube.
Never install your tire with a tool or a tire lever, as you risk pinching or puncturing the inner tube.

Inflating the tire

Carefully inflate your tire to the pressure recommended by the manufacturer (visible on the tire sidewall in PSI or bars: 1 bar = 14.51 PSI).
Regularly check that your tire is in the correct position as you inflate it.

Pro tip

To prevent pinching and achieve the best performance, we recommend checking and pumping up your front tire as needed before each ride.

I bought these tubes to replace old ones that came with my pair of foldable bikes. After more or less one year, there has been flat tires out of nowhere (no punctures on tyres or evidence like nails or thumbtacks). It just got old and weaker sections end up leaking.
