CST Premium bicycle inner tube, suitable for tires 20” x 3.5 - 4.5, with a wall thickness of 3.6 mm.
This inner tube features significantly thicker walls than standard tubes, making it nearly impossible to puncture. Ideal for use where durability is a priority.
The AV valve, also known as a Schrader valve, is the most popular valve used in inner tubes. These tubes can be inflated with a car pump or at gas stations with air. (Valve diameter: 8 mm)
Use of the ETRTO standard is recommended to ensure the inner tube fits the size of the bicycle tire.
