IT won't go down

Excellent for end of summer winter riding, without the worry of a puncture in the colder nights. 5 months in and they are still up.. ok weight is an issue, but I'll take that over 20mins of trying to fix a flat on a cold winters night..

Deflated

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.
Regards,

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.
Regards,

As expected. Good and normal one

I bought it online, and everything was perfect. Tried in my bike and went to drive some kilometers. All good, not issues.

Perfekt für Wege mit erhöhter Gefahr für Schäden

Hab den Reifen für mein MTB geholt und bin bisher sehr zufrieden, auch wenn ich noch keine Schäden hatte. Dennoch fährt man so immer mit einem gewissen Sicherheitsgefühl. Ich bin gespannt auf die erste Scherbe oder Nagel im Reifen ;)

Fahrradschlauch 26 Zoll

Der Schlauch macht einen wertigen Eindruck, die Montage verlief wie erwartet Problemlos einfach. Das Ventil ist ausreichend lang. Ob der Reifen sich selbst repariert wird der Langzeittest zeigen.

Buen funcionamiento

Cumple con su función es efectiva

Hola Jorge.

En primer lugar, agradecerte el tiempo que te has tomado en depositar una valoración sobre nuestro producto. Así, como la confianza que depositas en Decathlon para realizar tus compras de material deportivo específico de ciclismo.


Estamos encantados de que el producto cumpla con las expectativas, recuerda que si tienes un pinchazo dejar actuar al líquido para que selle completamente y posteriormente volver a darle presión a la rueda.


Reciba un cordial saludo, que tengas un buen día.

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.
