heavily inflated.
Otherwise irreversible damage will occur!
Before fitting, please slightly inflate the tyre to check for leaks!
When mounting, inflate the tyre by 0.5PSl first.
Make sure the inner tube is pressed against the
inner wall of the tyre and then press to adjust the tube
Inflating more than 6psi empty will
result in an unrepairable swell.
Remember to never exceed 6psi when pumping empty.

These are fantastic tpu tubes. I already had them on my bike but wanted an extra set for long ride spare tubes. they are so light and in my experience quite strong. I don't think I'll use another tpu tube, these are perfect for me

absolument désastreux : c'est la deuxième fois que je fais l'essai de ces chambres en TPU (d'abord RideNow ) avec cette fois la marque ThinkRider. J'ai suivi scrupuleusement les instructions en faisant plus qu'attention et une chambre à air était crevée et l'autre si apparemment se gonflait au bout de quelques minutes elle était à plat! Je n'ai même pas pu rouler avec ses chambres à air et déjà que j'en ai 2 qui ne fonctionnaient pas normalement je vais demander le remboursement pour les autres (Même résultat avec RideNow) je vais revenir aux chambres en butyl!
