for the moment nothing to report
Very disappointed with this product. use as a replacement for an old inner tube. 1st mountain bike outing and puncture after 20 minutes. . Tear in the air chamber at the joint with the valve.
Used in mountain biking, it punctured easily. It is very delicate in replacement maneuvers
The camera was punctured, I broke the box and I can't change it.
good quality/price ratio
I've been using them for a long time with other tires and I'm happy with them. I have not punctured and I am reliable ok
I have only put one and it has lasted me 3 outings, a lot of trouble on the roads
Great team in Agde
Good and effective product
RAS for the moment to see in the longer term High weight
GOOD
Exactly meets my expectations. The valve a bit long but it still works Good product
Until I deflated them to replace the tires everything was fine, when I reassembled they sold the heat seals in the same place and they can't be repaired ... a rip off
Excellent value
I recommend its anti-puncture inner tubes, compatible with 26" 2.1 tubeless ready BTWIN tires from Decathlon
Additional Product Information
Composition

How to choose your inner tube
Check the information indicated on the sidewall of the tire (diameter and width). For example, 26 x 2.00 means your tire is 26 inches in diameter and 2.00 inches in width.On the sidewall, you will also find the dimensions in mm in international ETRTO measurements.For example 50-559 means the tire is 50 mm wide with an inner diameter of 559 mm (or 26 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.
Fitting 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 tire so that it fits inside the rim.Take care not to pinch the inner tube when fitting.
Mounting the tire
Start by mounting the tire onto the wheel on the opposite side to the valve.Finish mounting it on the valve side to avoid pinching itNever 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 prevent any puncture from pinching and to achieve the best performance, we recommend checking and, if necessary, pumping up your front tire before each ride.
