    Let down

    Bought 2 of these. One to replace a used inner tube and one as backup to carry with me. Now onto my second one as the first one lasted about 15miles. Whilst riding the tube simply failed going totally flat within seconds. Upon inspection the tube has simply failed splitting around the valve and cannot be fixed. Fingers crossed this is a one off but now I'm conscience of a potential problem. Won't buy this product again.

    Thank you for your review of this innertube. I have forwarded your feedback on to the team in charge of this item.
    If the tube was faulty, please return it to us for a refund or an exchange with your receipt.

    Simple but effective

    Ideal for MTB and reasonably priced

    Great value

    These tubes work really well, as good as the big brands and far cheaper so represent great value.

    Good quality product

    Manufacturing quality of both rubber & valve is good. Sizing is perfect. No complaints at all.

    Accomplishes its purpose.

    Great choice for those ones who own a cycle brand different from the house's one, at an unbeatable price. Though 48mm valve is a bit long for my tyre, I recommend it.


    Dobry kup

    solide aber schwer

    Solider Schlauch, relativ schwer, der Ventileinsatz ist nicht wechselbar, gut als Reserve. Würde ihn aber nicht im Race fahren.


    alles okay

    Preiswert aber gut

    Beim MTB gehören Schläuche zu den Verschleißteilen. Diese Schläuche habe ich durch Zufall im Shop gesehen und als Ersatz einfach mal auf Verdacht gekauft. Vor ein paar Tagen habe ich dann schon den ersten verbaut. Sind zwar nicht eben Leichtgewichte, machen aber einen sehr robusten Eindruck. Bin bisher vollauf zufrieden!

    Additional Product Information

    How to choose your inner tube

    Check all the information indicated on the sidewall of the tyre (diameter and width). For example, 29x1.90 means that the tyre is 29 inches in diameter and 1.90 inches wide.On the tyre sidewall you will also find the dimensions in mm in ETRTO international units.For example, 50-622 means that the tyre is 50mm wide with a 622mm internal diameter (approx. 29x2.00).

    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 rim strip and that it is positioned correctly.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 mounting the tyre at the valve.Finish mounting the tyre opposite the valve to avoid pinching the inner tube.Never mount your tyre with a tool 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 avoid punctures from pinching and for the best tyre performance, we recommend that you check your tyres and inflate them to the suggested pressure before every ride.
