The GT Bikes 20" BMX inner tube is designed for tire widths from 20 x 2.1" to 20 x 2.4" and is therefore compatible with typical street, park, or trail setups in the BMX sector. It offers the necessary volume reserve for wide tires without warping or folding during installation.
The installed AV/Schrader valve is standardized and can be filled with all common pumps – whether floor pump, compressor, or gas station pump. The valve base is reinforced, which prevents air loss and valve breakage.
Weighing in at around 155g, the tube is ideally suited for practical use: robust enough for heavy loads, light enough for responsive setups. The fit is perfect for wider rims – a clean fit, reliable sealing, and quick installation.
