29" wheels and tires with a Presta valve (small valve).
The liquid in the inner tube seals small punctures (< 3 mm).
The hole is sealed while you ride.
I normally buy the original Slime tubes and never had a problem. Bought two of these and both failed a FPS had to carry my bike crack to the car.
If you feel it is faulty and/or not fit for purpose, please return the item to us.

Not had a puncture yet since installing them as I am aware. So gatherthey must be working as I’ve done quite a lot of off-road riding on them.
Very good good inner tube, had puncture, sealed straight away, continued my ride trouble free.
Bought this weeks ago for my flatmate who ride bikes to commute to work everyday. He said it was really useful and the instruction made it easy to install. He likes this type of inner tube sooooo much.
I am a beginner for decathlon product, for this product, it looks good on the website. And I will try later.
I got a nail through my tyre and it went flat. Doesn't do want the picture implies. waste of money and has sludge rolling around inside the tube. better of getting a normal inner tube
If you are not happy with the innertube, you can of course return it to us for an exchange.

Poor valve means both my pumps will not hold and thus cannot get more than 40 PSI. Bike / Tyre requires 65 psi. Adapter won't hold on to valve so even 40 psi is a guess. Veryt frustrating. Add to that the vide shows a schreder valve in use and you wonder why. Maybe the video makers could not get it to hold either? Bought two. Usually I would drill my rims to use the car type schreder valves but thought I'd give these a chance. WRONG!
Sorry to hear about the issue you have come across with getting the self healing tube to inflate properly. Having used both the 27.5 & 29 version in store I haven't come across this issue which leads me to think there must be a fault with the 2 (batch) that you bought. I would suggest to take the tube & wheel into your local store to see if they have the same issue when trying to inflate over 40psi. If so I'd get them to exchange the tubes for you and fit them to make sure the same problem doesn't occur.

Produit conforme à mes attentes, enfin fini la crainte de la crevaison. Facile à mettre en place.
Surtout il faut mettre la valve en haut pour gonfler la chambre
Valve trop longue
pas de crevaison pour l instant
Plus solide qu'une chambre à air standard

Check the information indicated on the sidewall of the tire (diameter and width). For example, 27.5 x 1.90 means a tire with a 27.5-inch diameter that is 1.90 inches wide. On the tire sidewall, you will also find the dimensions in mm in ETRTO international units. For example, 50-584 means your tire is 50 mm wide with an inner diameter of 584 mm (approx. 26 x 1.90).
Remove the used inner tube using B'Twin tire levers (item code 8047839).
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
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.
Start by mounting the tire onto the wheel on the opposite side to 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.
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.
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.
To guarantee optimal quality, 100% of our inner tubes are inflated for a period of 8 hours.
Carry your inner tubes in a container that protects them from perforations (tool case, original packaging, etc.).
Wheel size is printed on the sidewall of your tire. Always carry a spare inner tube and a pump.
