Super light inner tube TPU 700/18C-28C

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, to finally get 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.

Unimaginable lightness and compactness

Inspired by the road bike inner tube, Race Formula offers three versions: 36g, 24g and 19g. The lightest version, 19g, is even lighter than the self-filling liquid injected into tires under vacuum.

What's more, the footprint is reduced by 50% compared with the volume of an ordinary inner tube, allowing it to be stored in a pocket or tool bag.

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. Compressors are not recommended either.

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 (climbs, long rides where you leave in the morning and return in the middle of the day...).

Inflate progressively.
