When do you need a new inner tube?
You replace a bicycle inner tube when your current tube is punctured or frequently loses air. This FISCHER inner tube is suitable for 28-inch bicycles and ensures your tyre stays properly inflated. You need a new inner tube in case of a puncture, valve damage or wear of the rubber.

Why choose this 28-inch variant?
This inner tube fits various 28-inch tyre widths according to the ETRTO standards 37-622 to 45-622. This makes it suitable for narrow racing bike tyres from 28 x 1.35 to wider touring bike tyres of 28 x 1.75. So you can use one inner tube for different tyre types within the 28-inch size.

The advantage of a car valve
This inner tube has a car valve (also called a Schrader valve) instead of a French valve. The car valve is more robustly built, and you can inflate it at any petrol station or with a regular car pump. This makes it more practical for everyday use, especially with e-bikes and city bikes where more pressure is needed.

Note the valve length of 35 mm
The valve length of 35 mm is suitable for rims of normal thickness. Before buying, check that this length passes through your rim without being too short or too long. Valves that are too short are difficult to inflate, while valves that are too long can break off. So measure the thickness of your rim to be sure of the right fit.
