Inner tube 18 inch for tire 3.0 MM 110/100-120/100-120/90-130/80-130/90-140/70-140/80

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-resistance tubes (double the resistance compared to standard inner tubes).
Among its main strengths is the inflation valve. The valve is usually the weakest point of the inner tube, and most of our inner tubes use the TR6 standard instead of TR4, which is common in many inner tubes on the market. This specific standard allows for an elliptical rather than circular reinforcement area, ensuring greater tear resistance while remaining very flexible and adhering to the rim.
