Deux crevaisons en trois sorties sur deux chambres à air différentes.
inutile de dire que la fiabilité n'est pas au rendez-vous;
Il suffit de les gonfler, hors du pneu, pour s'apercevoir quelles sont déformées, ce qui signifie que l'épaisseur du caoutchouc n'est pas homogène impliquant donc des zones plus fragiles.
Mais c'est sans doute normal pour du made in china !
Réponse de la marque
Bonjour Monsieur,

Merci d'avoir pris le temps de déposer un avis sur la CHAMBRE A AIR 700X18/25 PRESTA 48MM.
Je suis sincèrement navrée que le produit ne vous convienne pas.

Une crevaison n'est pas toujours la faute de la chambre à air, il peut y avoir plusieurs raisons : l'état de votre pneu, l'état de la route, du fond de jante ou un léger pincement au moment du montage.
Sachez que lorsque vous gonflez votre chambre à air, il est primordial de ne pas la gonfler hors de votre pneu, car la matière fait que si elle n'est pas renfermée dans son pneu, des hernies apparaîtront même sans avoir dépassé un ou deux bars, vous pouvez la pré-gonfler pour lui donner sa forme mais pas plus que nécessaire.
Nos chambres à air subissent des contrôles avant leur commercialisation, mais il se peut que les vôtres ont eu un défaut lors de leur conception et je m'en excuse.
Pour vous permettre d'apprécier la qualité de nos chambres à air je vous invite à vous les faire échanger lors de votre prochaine visite dans nos magasins Decathlon.

Je reste à votre disposition si nécessaire.

Je vous souhaite une très belle journée.

Sportivement

mais le modèle est peu résistant à plus haute vitesse et les crevaisons de fatigue arrivent vite

Pas pincée mais a éclaté à 9 bars incompréhensible
Réponse de la marque
Bonjour Monsieur,

Merci d'avoir pris le temps de nous partager votre avis sur cette chambre à air 700 valve Presta.
Je suis navré du souci que vous avez rencontré et m'en excuse.
Une pression de 9 bars est vraiment haute mais il est tout à fait anormal que la chambre à air explose.
La cause principale d'un éclatement est le pincement comme vous l'énoncez ou cela peut également provenir de votre fond de jante mal positionné ou abîmé. Penser à le vérifier.
Il faut également être vigilant à ne pas gonflez trop votre chambre à air hors du pneu, cela peut provoquer une hernie voire un éclatement.
Je vous propose de vous faire échanger votre produit sur présentation de ce mail et suis certain que vous pourrez profiter pleinement de la qualité de nos produits lors de vos prochaines sorties à vélo.
Merci pour votre fidélité.
Cordialement

Nicolas
