Technical Information

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).
Removing an inner tube
Remove the used inner tube using B'Twin tyre levers (item code 8047839).
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
Mounting 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 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 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 with a screwdriver 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 best tyre performance, we recommend that you check your tyres and inflate them to the suggested pressure before every ride.

Failed right out the box
Manufacturing defect ; small hole in seam meant this failed before I could use it. Not much good when you are half way to nowhere and have a genuine puncture .

Искам да купя
Used for 1 week or less
искам да купя но няма
Много чакане за този продукт :(
Used for 2 to 8 weeks
Редовно търсене из цяла България за продукта и много чакане но иначе съм доволен от него.
Used for 3 to 6 months
Препоръчвам. Дори при наличието на външни тела, забити във вътрешната гума (в моя случай), тя продължи да поддържа достатъчно налягане, докато не я демонтирах. Учудващо за продукт с такава цена.
Haltbarer 29 Zoll Schlauch
Used for 3 to 6 months
Jeder Schlauch, ob teuer oder günstig verliert Luft mit der Zeit. Wenn es kein Lightschlauch sein muss ist man mit diesem sehr gut bedient. Er passt für die gängigsten Reifengrößen von 44mm-57mm. Zudem ist er sauber verarbeitet und kann als Eigenmarke von Decathlon mit teureren Premiumprodukten absolut mithalten.
Super Schlauch

Excelente Producto
Used for More than 2 years
Es un buen producto calidad a un precio asequible
Válvula escesivamente larga
Used for 2 to 8 weeks
No encuentro ninguna ventaja en esa válvula tan larga
Response of the brand
Hola Juan Ignacio, sentimos las molestias ocasionadas.

La ventaja esta que al sobresalir mas la válvula es mas fácil llegar a hinchar la cámara.

Te recordamos tienes 60 días para cambios o devoluciones.
