Did the job

new bike

The 2 stars is for the fact we bought a brand new bike just before lockdown and after a couple of rides had a flat tyre, with air coming from the valve. On returning the bike we had to pay for a new inner tube & fitting - - really had hoped the bike would have lasted a bit longer before having quite a few minor issues.

An inner tube

I haven't used it yet, I don't want to use it as this would mean I have a puncture, however, easy to locate in the decathlon store, great price as well.

Worst product ever.

This is the worst Decathlon branded product I've ever used. The quality of this inner tube is embarrassingly poor. I am currently on an all india trip on a rockrider st100 and the stock tubes and the extra tube I bought from Decathlon let me down multiple times. Multiple punctures throughout the day,that too without external causes. This problem stopped as soon as I replaced the inner tubes with a cheaper local brand. Never buying this again nor recommending it to anyone else.

Additional Product Information



  • 100% Rubber - Synthetic

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

Remove the old inner tube using B'Twin tire levers

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.
