Technical Information

How to choose your inner tube
Check the information indicated on the sidewall of the tyre (diameter and width). For example, 26 x 2.20 means your tyre is 26 inches in diameter and 2.20 inches wide. On the tyre sidewall you will also find the dimensions in mm in ETRTO international units. For example, 50-559 means a tyre that is 50mm wide and has an inner diameter of 559mm (approx. 26 x 2.00).
Removing an inner tube
Remove the used inner tube using B'Twin tyre levers (item code 8047839).
Checks to carry out before installing an inner tube
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.
Mounting the inner tube
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.
Mounting the tyre
Start by mounting the tyre onto the wheel on the opposite side to the valve. Finish mounting the tyre at the valve to avoid pinching the inner tube. Never mount your tyre with a screwdriver or a tyre lever, as you risk pinching and puncturing the inner tube.
Inflating the tyre
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.
Tip from the pros
To avoid punctures from pinching and for best tyre performance, we recommend that you check your tyres and inflate them to the suggested pressure before every ride.

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.
Response of the brand
I'm sorry to read that the innertube was punctured straight out of the box. This is highly unusual and I am unable to explain why it's the case in this instance.

Good budget tube

Good budget tube but my local store only has 48 mm valve stems, do they have anything shorter?
Good Price

Always carried, seldom used but worth having with you. Can't go wrong at the price
Tube - Presta
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.
Value for Money
Quality and VFM together.

Tube quality is good but valve design is bad
Used for 3 to 6 months
Dear Team, I'm using RR560 and Stock Tube was Kenda for my 27.5"x2.10" wheel. I took additional Presta valve tube for backup and once I used this spare tube, I found Presta Valve is not having any ring to tight it with rim so after installation, it was in loose - movable condition. the only disadvantage of this without tightening ring on valve, when I used mini hand pump, my two inner tubes, till date got damaged as due to multiple stroke while pumping, tube got damaged, where valve was attached. In your product picture, you are displaying valve with that ring but in the packet, it's plain.
