Technical Information

How to choose your inner tube
Check the information indicated on the sidewall of the tyre (diameter and width). For example, 700 x 35 means your tyre is 700mm in diameter and 35mm wide. On the sidewall you will also find the dimensions in mm in international ETRTO. For example: 35-622 means your tyre is 35mm wide with an inner diameter of 700mm (so 700 x 35)
Removing an inner tube
Remove the old inner tube using the B'Twin tyre tools (item code 8047839).
Checks to carry out before installing an inner tube
Check the condition of your tyre and replace it if necessary. Make sure no objects are lodged in the tyre. Check the condition of your tyre 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
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 tyre so that it fits inside the rim. Take care not to pinch the inner tube when fitting.
Mounting the tyre
Start by mounting the tyre from the opposite side of the valve Finish at the top of the valve to avoid pinching Never use a screwdriver or tyre lever to mount the tyre or you could pinch the inner tube and puncture it.
Inflating the tyre
Inflate your tyre carefully, to the pressure recommended by the manufacturer (visible on the tyre sidewall in PSI or bars, 1 bar = 14.51 PSI). Regularly check that your tyre is in the correct position as you inflate it.
Tip from the pros
To avoid punctures from pinching and for best tyre performance, we recommend that you check your tyres and inflate them to the suggested pressure before every ride.

Self sealing tubes
Used for 3 to 6 months
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....
Used for More than 2 years
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
Used for 1 week or less
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.
It popped when I inflated it!

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.

Cámara muy buena.
Muy buen resultado, evita muchos pinchazos que una cámara normal no podrías evitar.
Es el mejor invento
Used for More than 2 years
Desde que se sustituyó el líquido verde por este naranja estas cámaras son eternas no pinchas nunca, otra ventaja es que cuando cambias cubiertas todo está limpio y no tienes que limpiar el líquido como en las tubeless, pesa más pero me gusta su funcionamiento. Gracias Decathlon!!!
Muy buen producto
Ya no pincho como antes. Muy recomendable
Used for 2 to 8 weeks
