It is a tube. fits 28mm tires. Tick.

it is a tube. I could have purchased any tube, the Decathlon tubes are just as good and any other 28mm ready tubes. I am not racing.

the tube is leaky

The tube is leaky and not holding air. Once installed and pumped, the air leaked out entirely after a few seconds of ride. It's not worth it.

Cheap for a reason

The valve didn’t have a thread to fix in place. Also the tube itself only lasted an hour before exploding!

decent quality inner tube

The tubes are decent quality. One watch point is that quality control is not consistent. I've had some tubes that had failures from manufacturing flaws.

How to choose your inner tube

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. 27.5 x 2.00).

Removing an inner tube

Remove the old inner tube using a tire lever.

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.
