Not that great

Added these to my bike and on it's first ride at just below the tyres recommended psi did a small jump and when I landed it had a rear blow out and threw me off. Wasn't happy at all, luckily rims were not damaged, but could have been costly.

Thank you for taking the time to review these innertubes. Whilst they are effective at preventing small thorns and the like from leading to a puncture, they offer little protection against tyre pinching. We always recommend you follow the tyre pressure recommendations as stipulated by your tyre manufacturer. Looking at going down the tubelss route may be a more sensible option as this set up is particularly suited to preventing pinch flats.

I bought the inner tube but was a bit disappointed had when I got home I didn't have the correct fitting on the pump to inflate the tyre.

Patch it

Already bought one of these when fitting a new tyre to my partners bike, bought a second to fit when the requested tyre is in stock. First time tried these but you don't know until you try them, so far no problems with the first one I fitted, despite a couple hundred miles so far on thorn covered tracks, I think the ungraded tyre helps to.

Highly recommended tube.

I've had these tubes in for around 4 months now, had no trouble fitting and haven't noticed the extra weight as some people suggested I would. I am really enjoying going out with the club and not being the one with the punctures. I'm out several times a week over some rough terrain and I know there are several thorns that have gone in them but they are still fully inflated so very happy. Some say the downfall of these tube are that if they deflate and you need to repair you will probably find several punctures and you would have to repair them all before re inflating. My answer to this, if I found the tube had multiple punctures that needed repairing, for the sake of £3.99 I would just replace with a new one. If every set lasts over 4 months I'm more than happy with that.


Puncture twice in one month. Didn't find any self sealing things.

Selbstreparierend war leider ein Schuss in den Ofe

Nachdem ein kleines Loch in den Schlauch kam, hatte ich lediglich einen Platten. Von selbstreparierend war da keine Spur. Zu Hause den Schlauch rausgenommen und nochmal aufgepumpt. Sofort das Loch gefunden, da dort die sagenumwobene Flüssigkeit einfach nur austrat, aber das Loch nicht, wie in der Beschreibung angegeben, von innen versiegelte. Die Größe des Loches war lediglich die einer Nadelspitze...

Guten Tag,

vielen Dank für deine Bewertung zu dem selbstreparierenden Fahrradschlauch von B'TWIN. Wir bedauern, dass du mit diesem Produkt nicht zufrieden bist. Bei kleineren Rissen (<3 mm) sollte die beinhaltete Flüssigkeit das Loch schließen. Schade, dass es bei dir nicht der Fall war.

No ha durado un asalto

Sorprendentemente no ha durado una salida....parece que no suelen romperse según post venta pero en este caso si.

Me siento segura al andar con mi nueva cámara de aire autorreparable ya que no tengo que estar preocupándome si pincho en el camino. Además puedo inflar la cámara con el mismo inflador adaptando el pico.

How to choose your inner tube

Check all the information indicated on the sidewall of the tyre (diameter and width). For example, 27.5 x 2.00 means a tyre with a 27.5-inch diameter that is 2.00 inches wide.On the tyre sidewall you will also find the dimensions in mm in ETRTO international units.For example, 50-584 means that the tyre is 50mm wide with a 584mm internal diameter (approx. 27x2.00).

Removing an inner tube

Remove the old inner tube using B'Twin tyre levers.

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

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 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 onto the wheel on the opposite side to the valve.Finish mounting the tyre at the valve to avoid pinching the inner tube.Never mount your tyre with a screwdriver or a tyre lever, as you risk pinching and puncturing the inner tube.

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 prevent any puncture from pinching and to achieve the best performance, we recommend checking and, if necessary, pumping up your front tyre before each ride.
