    Product feature
    1. How to choose your inner tube
      Check the information indicated on the sidewall of the tyre (diameter and width). For example, 26 x 2.20 means your tyre is 26 inches in diameter and 2.20 inches in width. On the sidewall, you will also find the dimensions in mm in international ETRTO measurements. For example 50-559 means the tyre is 50 mm wide with an inner diameter of 559 mm (or 26 x 2.00).
    2. Removing an inner tube
      Remove the used inner tube using B'Twin tyre levers (item code 8047839).
    3. What to check before installing your new 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.
    4. 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 rims. 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.
    5. 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 using a screwdriver or a tyre lever as you risk pinching and puncturing the inner tube.
    6. Inflating the tyre
      Inflate your tyre carefully to the pressure recommended by the manufacturer (visible on the sidewall of the tyre in PSI or bars; 1 bars = 14.51 PSI). Regularly check that your tyre is in the correct position as you inflate it.
    7. Tip from the pros
      To avoid punctures caused by pinching and get more out of your tyres, we recommend that you check your tyre pressure before each ride and pump them up if necessary.

      Response of the brand
      Dear Pavan,

      Thank you for sharing your useful review. The puncture protect is definitely a very helpful product for off-road or regular users. We really appreciate you taking time to share your experience with us. Happy cycling

    • Failed to self-seal

      Chris (United Kingdom)
      Used for 1 week or less
      Punctured on only my second use (on not particularly rough roads/tracks). Self repair failed to work and I had to walk home and resort to the good old puncture repair kit.
      Response of the brand
      I'm sorry to read that the innertube did not seal itself. Holes made by thorns, small pieces of flint or small pinch flats should seal up with no issue as long as you keep on riding (important not to stop riding), the motion of the wheels spinning plugs the hole. If you continued to ride and the puncture persisted, the hole may have been too large.
      If you believe the item to be faulty then please feel free to return it to us for a refund or an exchange.

    • not worth buying

      Puneeth (India)
      Used for 1 week or less
      not even 10days usage , already the tube got punctured once. NO SELF HEALING.
      Blindly dont believe this product
      Response of the brand
      Hello Punith,

      Thank you for taking the time to give us your review. The inner tube usually heals staple pins and smaller punctures. It may not be able to heal nail piercings. I suggest you try a tire liner to reduce the number of punctures.  I remain available for more questions.

    • Failed as a spare, faulty valve

      Yak (Singapore)
      Used for 1 week or less
      Intended as a spare, had a puncture and did a road side swap, only to realise that the tube had a faulty valve and could not inflate. Maybe I just have a stroke of bad luck.
      Response of the brand
      Hi Yak, thanks for your feedback! We will definitely share it with the Btwin product manager. You may bring the inner tube back to any of our stores for an exchange!
