Great bought as a present
Luckily not had to use yes so can’t comment
Bought 2 of these. One to replace a used inner tube and one as backup to carry with me. Now onto my second one as the first one lasted about 15miles. Whilst riding the tube simply failed going totally flat within seconds. Upon inspection the tube has simply failed splitting around the valve and cannot be fixed. Fingers crossed this is a one off but now I'm conscience of a potential problem. Won't buy this product again.
If the tube was faulty, please return it to us for a refund or an exchange with your receipt.

Ideal for MTB and reasonably priced
These tubes work really well, as good as the big brands and far cheaper so represent great value.
picked up bike on Friday afternoon and rode it to York and scarborough Saturday and sunday. no problems with gears slipping as I thought there would be.
Will be stocking up on these tubes
It is very good product
Very sad, teared tube at the valve root , As a cyclist enthusiasts and as a decathlon customer , it is sad, My weakened is ruined , trust is shattered,

Simply go for it
Manufacturing quality of both rubber & valve is good. Sizing is perfect. No complaints at all.
Great choice for those ones who own a cycle brand different from the house's one, at an unbeatable price. Though 48mm valve is a bit long for my tyre, I recommend it.
cheapest...lasting too..

How to choose your inner tube
Check all the information indicated on the sidewall of the tire (diameter and width). For example, 29x1.90 means that the tire is 29 inches in diameter and 1.90 inches wide. On the tire sidewall, you will also find the dimensions in mm in ETRTO international units. For example, 50-622 means that the tire is 50 mm wide with a 622 mm internal diameter (approx. 29x2.00).
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 rim strip and that it is positioned correctly. 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.
