Je ne suis pas satisfaite de ce produit. Bizarrement, la valve en alu est toute lisse et il n'y a pas de possibilité de resserage via un "écrou" à la base de la valve pour éviter de voir le trou qui se trouve sur la roue et par lequel sort la valve. Cela fragilise du coup la chambre à air au niveau de la valve qui risque de se frotter au trou présent sur la roue.

j'ai acheté cette chambre à air pour mon vélo, j'ai repris le même emballage que lors de mon précédant achat pour être sûre d'avoir les bonnes dimensions : elle s'est avérée trop grande.

Bonjour Madame.


Je regrette que votre achat ne vous ai pas convenu.

Afin de vous assurer de la bonne dimension, une seule et bonne solution :

Se référer au mesures indiquées sur le flanc du pneu, soit en pouces (mesures anglo-saxonnes) soit ETRTO (mesures métriques).

N'hesitez pas à demander conseil et à vous faire échanger le produit lors de votre prochain passage.

Bonne journée

  • 10% Brass
  • 90% Rubber - Isobutylene isoprene rubber - butyl

How to choose an inner tube

Check the information indicated on the sidewall of the tire (diameter and width). For example, 26 x 2.20 means your tire is 26 inches in diameter and 2.20 inches wide. On the tire sidewall, you will also find the dimensions in mm in ETRTO international units. For example, 50-559 means a tire that is 50 mm wide and has an inner diameter of 559 mm (approx. 26 x 2.00).

Removing an inner tube

Remove the old inner tube using B'Twin tire levers

Checks to carry out before installing an inner tube

Check the condition of your tire and replace it if necessary. Make sure no objects are lodged in the tire. Check the condition of your tire 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

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 rim. Put the inner tube entirely inside the tire so that it fits inside the rim. Take care not to pinch the inner tube when fitting.

Mounting the tire

Start mounting the tire at the valve. Finish mounting the tire at the valve to avoid pinching the inner tube. Never mount your tire with a screwdriver or a tire lever, as you risk pinching and puncturing the inner tube.

Inflating the tire

Inflate your tire carefully, to the pressure recommended by the manufacturer (visible on the tire sidewall in PSI or bars, 1 bar = 14.51 PSI). Regularly check that your tire is in the correct position as you inflate it.

Tip from the pros

To avoid punctures from pinching and for best tire performance, we recommend that you check your tires and inflate them to the suggested pressure before every ride.
