The CST 28-inch bicycle inner tube is designed for use on city and trekking bikes and covers several common tire widths. Made from elastic butyl rubber, it offers consistent airtightness and uniform wall thickness. The sizes indicated on the tube ensure accurate identification and easy installation. The integrated 40 mm Presta valve is particularly suitable for narrow rim profiles. Thanks to its material properties, the tube reliably conforms to the tire and is a solid choice for everyday use, commuting, and longer tours.
