The heavy-duty inner tube comes with a size of 18’x1.75’/2.25′ and a valve type of AV32MM (45/57-355). Our inner tubes have enhanced ductility, allowing them to handle heavy loads effectively. This expanded scope of application makes them perfect for various biking conditions.

One of the standout features of our bike tubes is the new upgraded thicker inner tube. This tube weighs 200g, which is about 32.5% heavier than conventional tubes that typically weigh 151g.
