does the job, see the tightness over time
Horrible product. The camera had a puncture when putting the new one in, out of its box. I ordered a replacement, this one is complete, but it doesn't hold air for more than 6 hours, then it starts to deflate. Horrible product.
The price does the job.

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, 50-584 means that the tire is 50 mm wide with a 584 mm internal diameter (approx. 26x2.00).
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 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.
