Chambre à air 18 pouces 130/90

The inner tubes are made of natural rubber and are offered with two different thicknesses depending on the use:
The 2.5 mm version is the lightest (double strength compared to the standard inner tube)
The 4.0 mm (UHD) version is heavier but able to withstand extreme stresses!

This tube is absolutely exceptional when it comes to puncture resistance.

Among its main strengths we find the inflation valve.

The valve is normally the weakest point in the room and our rooms use only the TR6 standard instead of TR4 like most air chambers on the market.

This particular standard makes it possible to have an elliptical and non-circular reinforcement zone, which guarantees greater resistance to tearing, while remaining very flexible and adherent to the rim.
