Inner tube 19 inch for tire 3.0 MM 110/90 - 120/80 - 120/90

The inner tubes are made of 100% natural rubber and are available in three different thicknesses depending on the use:
The 3.0 mm version is the lightest of the high-strength tubes (double the strength of standard inner tubes)
Among its main strengths is the inflation valve. The valve is usually the weakest point of the tube, and our tubes, in most sizes, use the TR6 standard instead of TR4, unlike most inner tubes on the market. This particular standard allows for an elliptical rather than circular reinforcement area, which guarantees greater tear resistance, while remaining very flexible and adhering to the rim.
