Ultralite TPU Tube

Rigorous research and development design

In order to ensure that the small inner tube can unleash great energy during cycling, RideNow has made a lot of efforts and attempts from material formulation to production technology, and ultimately obtained the Race Formula inner tube you see.

High quality air valve

RideNow uses special reinforcing materials to make TPU inner tube valves, which are structurally stable, sturdy, and durable. 

Unimaginable lightness

Taking roadbike inner tube as an example, Race Formula offers three versions: 36g, 24g, and 19g. The lightest 19g version is even lighter than the self replenishing fluid injected into vacuum tyres.

Rich product models

Race Formula, as the world’s most popular TPU inner tube series, offers up to 40 different types of products. The rich product covers almost all types of inner tubes used in bike wheels.

TPU+metal composite valve

Race Formula has recently launched TPU+metal composite valve, providing stronger, more durable, and superior airtightness assurance.

Detachable presta valve cores

The new TPU+metal composite valve features a detachable core design, making it convenient for users to maintain or replace the core at any time. It is also compatible with threaded extension valves.

IMPORTANT WARNING: This chamber should not be inflated when not installed, otherwise it will cause irreversible damage.

Inflate a small amount until the chamber is somewhat round in shape.

It is not possible to use CO2 cylinders due to pressure and temperature changes.

It is not advisable to use compressors.

It is advisable to lower the pressure by 1kg than what we would do with a normal butyl chamber when inflating the wheel, to ensure that you do not have problems with changes in temperature (climbing mountain passes, long outings where you leave in the morning and return to noon…).

Inflate little by little.
