Our inner tubes are tested continually by our professional teams, such as the U-19 PRO Racing Team and the MTB Racing Team.
To guarantee optimal quality, 100% of our inner tubes are inflated for a period of 8 hours.
Carry your inner tubes in a container that protects them from perforations (B'TWIN carry case, original packaging, etc.).
When installing your inner tube, inflate it slightly to avoid pinching and regularly check the correct pressure of the latter. Always have a spare inner tube and other repair accessories.
