    Product feature
    1. How to choose your inner tube
      Write down all visible information from the tyre sidewall (diameter and width). For example, 26 x 2.20 means your tyre is 26 inches in diameter and 2.20 inches wide. 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 (approx. 26 x 2.00 inches)
    2. Removing an inner tube
      Remove the old inner tube using B'Twin tyre levers (ref 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 the 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 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.
    6. Inflating the tyre
      Inflate your tyre carefully, to the pressure recommended by the manufacturer (check the sidewall, written in PSI or in bars: 1 bar = 14.51 PSI) Regularly check that the tyre is in the right position while inflating.
    7. 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.
    Product testing

    2. Storage advice
      Carry your inner tubes in a container to protect them from getting punctured (tool drum, original packaging…).
    3. Cleaning advice
      To get your wheel size, check the information on the tyre wall. Always carry a spare inner tube and a pump.

      Response of the brand
      I'm sorry to read that you have a flat tyre.
      I'm very interested to hear more about your puncture and why it did not remain inflated when you were riding. I want to feed this back to b'Twin as it will be very useful information to understand what went wrong. Would you mind replying to me?

      Used for 1 week or less
      I bought these after a spate of punctures and with a new tyre, set off confident on my commute, 15 miles in and a saftey pin had gone through the side wall. Never mind I thought i'll pull it out and my brand new self sealing inner tube can shine, spin the wheel still going down , put more air in still going down spin the wheel with more air still no joy spent as long trying to get it to seal as it did to change. Got home and part inflated it and the goo bubbled out of a small hole I left it hanging with the hole at the bottom hoping it might work. After a week and still not sealed I binned it, complete waste of time and money.
      it fitted the rim
      it didn't work
      Response of the brand
      Hi Darren,

      Thank you for taking your time to review the self healing inner tube.
      It is strange that the sealant did not work as it should, you have done everything correct in regards to keeping the wheel spinning etc to get the sealant into the hole. The only thing I can think of is that the hole was bigger than the 3mm that it will seal up to. I have been using the road version on my bike and it worked well after riding over some glass.

      I'd return the tube to your local store for an exchange/refund as it has not done the job it is designed for.
