Bought 1 last night to fit to get to work today. Already had 2 holes in it. Too late to return it so had to walk this morning. I'm not happy

Dear Sir,
I'm very sorry to read that you had two punctures so soon after only fitting it the night before.
Could you kindly reply to me with more details (where you were riding for example) as this is a worry for me.
If you are not happy with them, please return them to us for a refund or an exchange with your receipt.
I look forward to hearing back from you.

Self sealing tubes

Bought these for a CX Sportive (I didn’t want any punctures). Easy to fit but make your wheels quite heavy. One of the tubes after inflation sealed its valve, so I cant pump it up anymore. But it doesn’t seem to have lost any pressure (so I guess less of a problem than I first thought). Bought a spare tube to replace that one when it eventually deflates.

Good but....

These tubes do as they are promised, I had some thorns puncture my tube in a number of places but the sealant did it's job and kept the tube inflated....but...I have had the valves get stuck closed by the sealant which is a real pain in presta valves as you need to get a pair of pliers to try and undo it, not good if you need to pump your tyres up in the middle of nowhere !!.., last time the whole valve started unscrewing from the tube. I will recommend these tubes and would have given 5stars if it wasn't for the valve issues. I've taken to inflating my tyres with the valve at the top and I wait 5 mins for the sealant to clear from the valve before starting, it may help.

Worst tyre ever

Very annoyed. Fully checked tyre for debris. Fitted the tube in the tyre. Inflated tube, intending to pump it to about 55psi. It supposedly goes up to 65 psi. Massive bang and I got covered in gunk as the seam split in the tube. A badly made tube, will never be buying a puncture proof tube from Decathlon again. Shoddy workmanship from a brand I had previously trusted.

Dear Sir,
I'm sorry to read that the inner-tube split during installation.  All of our products are quality controlled at the production phase.
I have had a look at other customer comments on the same product and it's the first time we've received this feedback.  I will alert the product manager at b'Twin of the issue your encountered.
Please feel free to return it to us for a refund/exchange the next time you pop in to Decathlon Stockport.

Excelente producto

En lo personal se me solían pinchar muy fácil las llantas de la bici, pero desde que compré esa camara no eh tenido ningún inconveniente

Perfecta para pequeños pinchazos

Auto repara los pequeños pinchazos producidos por material vegetal como pequeños pinchos, semillas, ramas, siendo eficaz por mucho tiempo. La válvula se dobla facilmente si no se tiene cuidado al usar la bomba produciendo pérdidas de aire por la misma.

Practico MTB. el sistema de la cámara de aire antiponchaduras me ha resultado bastante práctico a la hora de andar en bicicleta por todo tipo de terreno, la única observación es que la válvula es demasiado frágil, factor con lo que he lidiado últimamente, ya que aunque la cámara responde o se conserva en buen estado en relación a las ponchaduras he tenido que cambiar y desechar cámaras prácticamente nuevas por el problema de la válvula

No se que decir

Uso la primera vez está cámara para hacer Pedales DE Hierro. La monto en la rueda trasera y a mitad de prueba, en una bajada rápida con salto y caída en piedra suelta, se revienta la cámara. igual pedi demasiado... De todas formas he comprado otra...

camara sin pinchazos

No es nada del otro mundo. tambien pinchas y cuando llenas de aire se tapona la valbula. Puede valer pero no noto gran diferencia

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 it 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.

Product testing

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

Storage instructions
