## Long description

Inner bicycle tube from FISCHER with a Dunlop (Woods) valve designed for 20" wheels with ETRO size 40-406 and a tube circumference/length of 50.80 cm. The tube is intended as a direct replacement for punctured or worn inner tubes on compatible 20" rims and standard tyres. Its dimensions and valve type provide an easy fit for common urban and leisure bicycles that use Dunlop-valve holes in the rim.
Advantages
The FISCHER inner tube combines a size-specific fit with a Dunlop valve for simple inflation and secure seating in rims that support Woods/Dunlop valves. Manufactured for everyday use, the tube offers consistent air retention and straightforward installation without the need for specialised tools. Its compatibility with ETRO 40-406 tyres ensures predictable performance when replacing worn or damaged tubes.

Key specifications
Valve type: Dunlop (Woods) valve
Wheel diameter compatibility: 20"
ETRO tyre size compatibility: 40-406
Tube circumference/length: 50.80 cm
Application: standard pedestrian/urban cycling use
How to use
Carefully remove the wheel from the bicycle and deflate the existing tube fully before extracting it from the tyre. Inspect the tyre and rim strip for sharp objects or damage. Partially inflate the new FISCHER tube to give it shape, then insert the valve through the rim valve hole and seat the tube evenly inside the tyre. Work the tyre bead back onto the rim, ensuring the tube is not pinched, then inflate to the tyre manufacturer’s recommended pressure. Refit the wheel and check that the valve sits straight and that the tyre runs true.
Usage recommendations
Maintain recommended tyre pressures to reduce the risk of pinch flats; regularly inspect tyre tread and rim strip for embedded debris before fitting a new tube. Use a pump compatible with Dunlop valves or an adapter when required. Store spare tubes in a cool, dry place away from direct sunlight.
