Thank you for the kind review about this inner tube! We really appreciate it! :)

Presta inner tube

All inner tubes from Decathlon are very durable and haven't given me any problems in over two years of use.

Valve not long enough

Good price and correct size.

Correct size and valve type. Only thing missing is the threaded valve retainer.

26 x1.2 inner tube

Needed these for my folding bike with 1.5 tyres. Price was very good, and they do the job perfectly. The tubes are for 1.2 to 1.5 tyres, not for wider tyres. They keep air very well, so I’m very happy with these inner tubes.

No thread on valve stem

I made a special journey to Decathlon to buy a narrow 26" presta inner tube but was disappointed. None of the narrow 26" tubes had a thread on the valve stem, despite the fact that all the other sizes of the £2.50 tubes were threaded. It is difficult to position the tube without the thread and knurled ring so I did not buy them. Incidentally, the picture here is wrong - it shows a schraeder tube.

Dear Sir,
I have forwarded your comments on to the product manger who is in charge of the innertubes.  I have asked him to change the image.
Please accept my apologies the incorrect image.

How to choose your inner tube

Check the information indicated on the sidewall of the tire (diameter and width). For example, 26x1.40 means that the tire is 26 inches in diameter and 1.40 inches wide.On the tire sidewall, you will also find the dimensions in mm in ETRTO international units.For example, 38-559 means that the tire is 38 mm wide with a 559 mm internal diameter (approx. 26x1.50).

Removing an inner tube

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 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.
