Great product. Comparable price and quality to most popular brands.
Tube punctured within7 days
It was ok
Perfect and at a great price !
Good value tube for MTB
These are a touch thinner than my usual inner tubes, but for the price, you can't complain. They do the job and you can't quibble with the price.
Got a flat and needed a new inner tube. Such a great price I bought a couple just to be on the safe side.!
Cheap but very much not cheerful. Replacing a punctured tube with this, only to find out it's already leaking air. Found the hole and repaired it with a patch and still leaks. In the end I patched up the original tube and gave up on this one. Usually like decathlon stuff but will not buy inner tubes from there again.

Good budget tube but my local store only has 48 mm valve stems, do they have anything shorter?
Always carried, seldom used but worth having with you. Can't go wrong at the price
What can I say about this. Got them on my backpack. Still there, so they don't run away by them self! Not to heavy to carry around. Hope I wont need to use them at all. Not too expensive, so it's fine if I don't use them.
good quality at affordable price
Hi There,

Tube blasted as soon as I started pumping air
Hello Vivek,
We regret the inconvenience caused due to this. Kindly reach out to the nearest decathlon store workshop, the technicians would diagnose the problem and replace the tube and help you know the right PSI for your tire tube.
Thanks & Regards,
Vinay

How to choose your inner tube
Check the information indicated on the sidewall of the tire (diameter and width). For example, 27.5 x 2.10 means that the tire is 27.5 inches in diameter and 2.10 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.
