A great product that's cheap and reliable. Had no problems fitting it and getting it to inflate. Just need to show my daughter how to change a inner tube now so she can do it next time.
Buen producto calidad precio
vraiment rageant de trouver des chambres à air de 650... et pas les pneus (en x23 par ex.) qui vont avec !!!
Pièce de remplacement de très bonne qualité.
produit conforme aux attentes
Je crève beaucoup moins depuis que j'utilise cette marque. Avant j'utilisais un produit made in china moins chère mais moins bon
Chambre a air reçu coupe dans sa boite
Je regrette le souci rencontré qui est indépendant de notre volonté.
Je vous propose de procéder à un échange dans votre magasin habituel.
Je parcours plus de 12000 kms par an et j'utilise toujours ces chambres à air.

Check the information indicated on the sidewall of the tire (diameter and width). For example, 27.5 x 1.90 means a tire with a 27.5-inch diameter that is 1.90 inches wide. On the tire sidewall, you will also find the dimensions in mm in ETRTO international units. For example, 50-584 means your tire is 50 mm wide with an inner diameter of 584 mm (approx. 27.5 x 2.00).
Remove the old inner tube using B'Twin tire levers
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
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.
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.
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.
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.
To guarantee optimal quality, 100% of our inner tubes are inflated for a period of 8 hours.
Carry your inner tubes in a container to protect them from getting punctured (B'Twin carry case, original packaging, etc.).
