How to choose an inner tube
Note all the information visible on the tire's sidewall (diameter and section). For example, 26 x 2.00 means a tire with a diameter of 26 inches and a width of 2.00 inches.
On the tire sidewall, you'll also find the dimensions in mm in the international ETRTO unit.
For example, 50-559 means a tire with a width of 50 mm and an inside diameter of 559 mm (i.e. 26 x 2.00).
Removing the inner tube
Remove the used inner tube using DECATHLON tire levers.
Checks before fitting an inner tube
Check the condition of your tire, and replace it if necessary.
Make sure there are no foreign bodies in the tire.
Check the condition of your rim tape. Even a slightly cracked rim base can lead to punctures.
Check your rim for any alterations that could damage your inner tube.
Fitting your inner tube
See our video before you start.
Pre-inflate the tube slightly to avoid any risk of pinching.
Insert the valve into the valve hole, making sure you use the correct type of valve for your rim.
Place your tube in the entire tire, pushing the tube so that it is positioned in the hollow of the rim.
Make sure you don't pinch the tube when you finally mount the tire.
Tire mounting
Start by mounting the tire opposite the valve.
Finish mounting at valve level to avoid pinching
Never mount your tire with a screwdriver or tire lever, as this can pinch and puncture the inner tube.
Tire inflation
Inflate your tire carefully, to the pressure recommended by the manufacturer (visible on the tire sidewall in PSI or bars, 1 bar = 14.51 PSI).
Regularly check that the tire is correctly positioned when inflated.
Pro tip
To avoid pinch punctures and get the best performance from your tire, we recommend that you check and, if necessary, re-pressurize your tire before each outing.
