Additional Product Information

Composition

How to choose your inner tube

Check the information indicated on the sidewall of the tire (diameter and width).For example, 27.5 x 2.20 means that the tire is 27.5 inches in diameter and 2.20 inches wide.On the tire sidewall, you will also find the dimensions in mm in ETRTO international units. For example, 50-584 means a tire that is 50 mm wide and has an inner diameter of 584 mm (approx. 27.5 x 2.00).

Removing an inner tube

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 is even slightly bent can cause punctures.Check that your rim does not have any other issues that could damage your inner tube.

Mounting the inner tube

Watch our video before you start.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 tire so that it fits inside the rim.Take care not to pinch the inner tube when fitting.

Mounting the tire

Start mounting the tire at the valve.Finish mounting the tire at the valve to avoid pinching the inner tube.Never mount your tire with a screwdriver or a tire lever, as you risk pinching and puncturing the inner tube.

Inflating the tire

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 your tire is in the correct position as you inflate it.

Tip from the pros

To avoid punctures from pinching and for best tire performance, we recommend that you check your tires and inflate them to the suggested pressure before every ride.
