    Details
    Product feature
    1. How to choose an inner tube
      Check the information indicated on the sidewall of the tyre (diameter and width). For example, 26 x 2.20 means a tyre with a 26-inch diameter and 2.2 inches wide. On the tyre sidewall you will also find the dimensions in mm in ETRTO international units. For example, 50-559 means a tyre that is 50 mm wide and has an inner diameter of 559 mm (approx. 26 x 2.00).
    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.

      Para dar aire con mi bomba se "fuerza" un poco la posición de la válvula y se me abrió una raja en la zona pegada a la válvula sin posibilidad de reparación. No tuve ningún pinchazo y la cámara quedó para la basura. Espero que en esta segunda cámara no me pase lo mismo.
    • Buena y barata

      Es muy difícil encontrar cámaras de este tamaño y mucho mas difícil a un precio tan barato.

      J'ai dû remplacer la chambre à air de mon fils qui a un petit BTwin évolutif.
      Cette chambre à air correspond en tous points aux caractéristiques du vélo mais le bémol et que j'ai dû acheter un embout spécifique car je n'ai pas fait attention c'était un embout vélo classique et que l'ancienne chambre à air avait un embout VTT
    • Excellent mais...
