HOW TO CHOOSE YOUR INNER TUBE? 

Your inner tube is a key part of your bike's tyre and is often the culprit when you suffer a puncture. Choosing the right inner tube and looking after it properly can therefore make a world of difference...

DECATHLON's cycling brand offers handy tips to help with your cycling practice.

You should choose inner tubes depending on three criteria: the type of bike, the type of valve and the tyre dimensions.

THE BIKE TYPE

Each bike needs a different tyre and therefore a different inner tube (except in the case of tubeless tyres, which have a "built-in" inner tube made from a waterproof membrane).

Whether you're choosing a mountain bike, road bike, hybrid bike, kids' bike or BMX, you should take care when choosing your inner tube.

THE VALVE TYPE

SCHRADER VALVES

Also known as an "auto valve," this type of valve lets you inflate your inner tube at service stations. It is easy to use and sturdy, as well as being compatible with classic bike pumps.

PRESTA VALVES

The thinner Presta valve is common on road bikes. You have to unscrew this kind of valve in order to inflate your inner tube.

TYRE'S DIMENSIONS

To find out what size inner tube you need, you can check your bike's tyre or your old inner tube.

The dimension will be given in the format "diameter × minimum width / maximum width".

A diameter of 700 mm is a 28-inch tyre.

A diameter of 650 mm is a 26-inch tyre.

For example, if your bike has a tyre with a diameter of 700 mm and a width of 20 mm, a "700 × 18/25" inner tube is what you need.

Remember to inflate your inner tubes to the pressure recommended on the tyre at least once a month.

You can also get self-repairing inner tubes: they contain a liquid that will fill holes measuring less than 3 mm.
