Membrane : 100.0% Rubber - Synthetic Valve : 100.0% Brass
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 to protect them from getting punctured (tool drum, original packaging, etc.).
Wheel size is printed on the sidewall of your tyre. Always carry a spare inner tube and a pump.
