The liquid in the inner tube seals small punctures (< 3 mm).
Optimized composition to guarantee your inner tube has a good seal.
How to choose your inner tube
Check the sidewall for tire information (diameter and width). For example, 26 x 2.00 means your tire is 26” in diameter and 2.00” in width.
On the sidewall, you will also find the size in mm according to ETRTO standards.
For example 50-559 means the tire is 50 mm wide with an inner diameter of 559 mm (or 26 x 2.00).
Removing an inner tube
Remove the old inner tube using Btwin tire levers.
What to check before installing your new 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.
Fitting your 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 by mounting the tire onto the wheel on the side opposite 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.
To prevent pinching and achieve the best performance, we recommend checking and pumping up your front tire as needed before each ride.
