20", 1.7 to 2.2 cross section tyresETRTO 44/57 - 406
Optimised composition to ensure your inner tube has a good seal.
Upon fitting the inner tube to the tyre with some air in it, it seems the tube is longer than the tyre. It kind of folds a bit (BTWIN Foldable bike) after fitting.Who knows if it's still folder once fully inflated. So far it still holds the tyre and works....
Bought a pair for my fold up bike and sons BOX. These are superior to the cheap innertubes sold by other shops.
I think maybe on this occasion it would have been better to have paid for a better quality tube
I'm sorry to read that you have had a puncture.
Peter Lazarus UK Market Manager DECATHLON
Good product with a video with clear instruction to change the tyre.
Quality product fits perfectly for Btwin bike
After getting the tube replaced, we found out a puncture again the next morning.
Thank you for taking the time to give us your feedback. Inner tubes and tires are wearable components and it is possible for punctures to happen due to external factors and internal problems like pinching and spoke piercing. Please get the wheel diagnosed again for any such signs. Feel free to write back if you have any questions.
Deepak Babu E-sport manager DECATHLON
I bought these tubes to replace old ones that came with my pair of foldable bikes. After more or less one year, there has been flat tires out of nowhere (no punctures on tyres or evidence like nails or thumbtacks). It just got old and weaker sections end up leaking.

Check the information indicated on the sidewall of the tyre (diameter and width).For example, 20 x 2.10 means that the tyre is 20 inches in diameter and 2.10 inches wide.On the tyre sidewall you will also find the dimensions in mm in ETRTO international units. For example, 50-406 means a tyre that is 50mm wide and has an inner diameter of 406mm (approx. 20 x 2.00).
Remove the old inner tube using B'Twin tyre levers
Check the condition of your tyre and replace it if necessary.Make sure no objects are lodged in the tyre.Check the condition of your tyre 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.
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 tyre so that it fits inside the rim.Take care not to pinch the inner tube when fitting.
Start mounting the tyre at the valve.Finish mounting the tyre opposite the valve to avoid pinching the inner tube.Never mount your tyre with a tool or a tyre lever, as you risk pinching and puncturing the inner tube.
Inflate your tyre carefully, to the pressure recommended by the manufacturer (visible on the tyre sidewall in PSI or bars, 1 bar = 14.51 PSI).Regularly check that your tyre is in the correct position as you inflate it.
To prevent any puncture from pinching and to achieve the best performance, we recommend checking and, if necessary, pumping up your front tyre before each ride.
