18 inch inner tube for tire 2.0 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 2.0 mm version is superior to the standard inner tube.
Among its main strengths is the inflation valve. The valve is normally the weakest point of the tube, and most of our tubes use the TR6 standard instead of TR4, which is common in 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.
