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.

2 puestas y las dos válvulas reventadas en el mismo día, por lo que me tuve que volver andado a casa...

Estimado Pedro.
Muchas gracias por tu comentario y siento mucho las molestias ocasianadas por nuestras cámaras de aire.
Si todavía las conservas, me encantaría que te acercaras a tu tienda Decathlon más cercana para que mis compañeros de ciclismo pudieran hacer una comprobación de las mismas para descartar un defecto de fabricación y poder proporcionarte dos cámaras nuevas.

Disculpa de nuevo y gracias por tu tiempo.

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

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 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.

Complementary products

You'll need a tire lever (reference 8047839) to change your inner tube. If you want to repair a punctured inner tube, you can use repair patches (reference 1779640) or self-adhesive patches (reference 8380935)



Product testing

To guarantee optimal quality, 100% of our inner tubes are inflated for a period of 8 hours.

Storage instructions

Carry your inner tubes in a container to protect them from getting punctured (tool drum, original packaging…).

Care instructions

Wheel size is printed on the sidewall of your tire. Always carry a spare inner tube and a pump.
