TECHNICAL INFORMATION

How to choose an inner tube

Note all the information visible on the tire's sidewall (diameter and cross-section). For example, 27.5x1.90 means a tire with a diameter of 27.5 inches and a width of 1.90 inches.
On the tire sidewall, you'll also find the dimensions in mm in the international ETRTO unit.
For example, 50-584 means a tire with a width of 50 mm and an inside diameter of 584 mm (i.e. approx. 27.5x2.00).

Removing the inner tube

Dismantle the used inner tube using the 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 objects in the tire.
Check the condition of your rim tape and its correct positioning.
Even a slightly cracked rim tape can cause punctures.
Check your rim for any alterations that could damage your inner tube.

Fitting the 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 on the valve.
Finish the mounting on the opposite side of the valve to avoid pinching.
Never mount your tire with a tool 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 every outing.
