Inner tube TPU 29 /622 1.9-2.5.

Rigorous research and development.
To ensure that the small inner tube can release high energy during cycling, RideNow has made many efforts and attempts, from material formulation to production technology, and has finally achieved the Race inner tube Formula that you see.
High-quality air valve
RideNow uses special reinforcement materials to manufacture TPU inner tube valves, which are structurally stable, strong and durable.

IMPORTANT WARNING: This inner tube must not be inflated when not installed, otherwise irreversible damage may occur. Inflate the inner tube slightly until it takes on a slightly round shape.
CO2 cylinders cannot be used due to changes in pressure and temperature. Nor is it advisable to use compressors.
It is advisable to reduce the pressure by 1 kg compared with what you would do with a normal butyl inner tube when inflating the tire, to ensure that there are no problems with temperature changes (mountain climbs, long hikes where you leave in the morning and return in the middle of the day...)
Inflate a little at a time.
