Product benefits

  2. Waterproof
    High quality valve that retains pressure.
Product feature
  1. How to choose your inner tube
    Check the information indicated on the sidewall of the tyre (diameter and width). For example, 27.5 x 1.90 means a tyre with a 27.5-inch diameter that is 1.90 inches wide. On the tyre sidewall you will also find the dimensions in mm in ETRTO international units. For example, 50-584 means your tyre is 50 mm wide with an inner diameter of 584 mm (approx. 26x1.90).
  2. Removing an inner tube
    Remove the used inner tube using B'Twin tyre levers (item code 8047839).
  3. 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.
  4. Installing the inner tube
    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 from pinching and for best tyre performance, we recommend that you check your tyres and inflate them to the suggested pressure before every ride.

    Though the numbers on tire matches with the tube, this tube is bigger for Btwin MyBike Size L and the tube that comes with bike with bike is 'RALSON' make and its thicker than the 'Btwin' make tube.
    Response of the brand
    Hello Praneeth, 

    Thank you for taking the time to give us your review. The inner tube is compatible with 26" bikes which mean it can go on all the wheels which are of the size 26". If the inner tube is little larger, it should be ok because the extra space will be filled up with air. in case you are feeling a bump at regular intervals after fully inflating the tyres, you have to stop using the bike and get a replacement inner tube. It is possible that the one purchased was defective.
