Waterproof

48 mm Presta (or French) valve to retain pressure well.

TECHNICAL INFORMATIONS

How to choose your inner tube

Check the information indicated on the sidewall of the tire (diameter and width). For example, 700 x 23 means your tire is 700 mm in diameter and 23 mm wide. On the sidewall, you will also find the dimensions in mm in international ETRTO measurements. For example: 23-622 means your tire is 23 mm wide with an inner diameter of 700 mm (so 700 x 23).

Removing an inner tube

Remove the used inner tube using B'Twin tire levers (item code 8047839).

What to check before installing your new 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.

Installing your 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 tire so that it fits inside the rim. Take care not to pinch the inner tube when mounting.

Mounting the tire

Start by mounting the tire onto the wheel on the side opposite the valve. Finish mounting the tire at the valve to avoid pinching the inner tube. Never install 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's 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.

Bonjour. Je suis triathlète. J'ai eu 4 crevaisons en 30 jours avec ces chambres, heureusement toujours à l'entrainement, jamais en course, dans le cas contraire, aurevoir le classement en tri. Rien sur ou à l'intérieur du pneu. A devenir parano, inspection de la jante, changement de pneu, vérification des pincements... rien y fait, ça crève, grosse crevaison, direct à plat sur la jante. Ces chambres bon marché ne tiennent pas la pression, au moindre point de pression sur la route, elles explosent. Produit catastrophique.A retirer de la vente.

Bonjour Monsieur,

Merci d'avoir déposé un avis sur le lot de 2 chambres à air 700.
Je regrette que ce produit ne vous ai pas satisfait et comprends tout à fait votre mécontentement et les conséquences que cela aurait pu avoir sur vos compétitions.
Il est très compliqué d'imputer la seule qualité de la chambre à air lors d'une crevaison, même en cas de crevaisons à répétitions.
De nombreux paramètres entrent en jeu :
- pincement au montage
- usure du pneu
- impureté restée dans votre pneu suite à la précédente crevaison
- pression insuffisante
- fond de jante mal placé
- routes en mauvaises état
- mauvaise série.....
Vous avez pris soin de vérifier de nombreux paramètres pour vous assurer que ce type de souci ne se reproduise pas.
Je suis sincèrement désolé pour ces désagréments et vous assurer que nous mettons tout en oeuvre pour éviter cela.
Je vous invite à vous faire échanger ou rembourser vos 4 chambres à air dans votre magasin habituel.
Bonne journée
Cordialement

Nicolas

Response of the brand
Bonjour Monsieur,

Merci d'avoir pris le temps de déposer un avis sur le lot de 2 chambres à air 700.
Je suis sincèrement désolé que ce produit ne vous ai pas satisfait et le regrette.
Lors d'une crevaison, il est compliqué d'imputer celle ci uniquement à la qualité de la chambre à air.
Je vous invite à vérifier le niveau d'usure de votre pneu, le bon état et le bon positionnement de votre fond de jante, le niveau de pression de vos pneus (un sous gonflage peut entrainer des crevaisons) et de bien vérifier qu'aucun pincement ne soit effectué lors du montage d votre chambre à air.
Pour vous permettre de tester de nouveau notre produit, je vous propose de vous le faire échanger dans votre magasin habituel.
Bonne journée
Cordialement
