When do you need a 24 inch inner tube?
You replace a bicycle inner tube when your current tube has a puncture or when you carry out preventive maintenance. This FISCHER inner tube is specially designed for 24 inch wheels and fits a wide range of tyre widths, from 24 x 1.5 to 24 x 2.125 inch. The car valve makes inflation easy with a standard bicycle pump or compressor.

Why this wide compatibility is handy
This inner tube supports many ETRTO standards (40-507 to 57-507), which means you can use one spare tube for different bicycles with 24 inch wheels. Whether you have a children's bike, BMX or compact city bike, the wide design adapts to different tyre widths. This saves you from having to keep several different inner tubes in stock.

Puncture resistance through special gel
What makes this inner tube special is its puncture-resistant property thanks to a special gel that automatically seals small holes up to 3 mm in diameter. When a nail, thorn or sharp object pierces the tyre, the gel ensures the puncture closes immediately. This means less bad luck on the road and fewer frequent repairs, especially useful for daily use or longer bike trips.

Practical fitting tip
When fitting, note the valve length of 35 mm – this suits standard rims, but check that your rim is not too deep. Always use a little talcum powder between the inner tube and outer tyre to prevent friction. When inflating a new inner tube, first pump it up at low pressure and check that the tube sits properly before reaching the recommended pressure.
