Camera d'aria per bicicletta FISCHER valvola Dunlop 30,5 cm (12 pollici) conforme ETRTO

FISCHER inner tube with a Dunlop (Woods) valve, 30.5 cm (12") in length, designed to meet ETRTO standards for compatible 12-inch tyres and rims. This tube is intended for repair and replacement in bicycles with small wheels, offering airtight sealing and reliable inflation when fitted correctly. The product suits urban bikes, children's bicycles and other small-wheel applications where a Dunlop valve is specified.

Advantages

The tube is manufactured to ETRTO-compliant dimensions to ensure consistent fit and performance with compatible tyres and rims. The Dunlop valve provides a widely used, serviceable valve type that can be inflated with standard pumps designed for Woods/Dunlop fittings. Made from standard inner tube rubber compound, it combines flexibility for easy installation and sufficient durability for everyday cycling conditions on small wheels.

How to use

Inspect the tyre and rim for debris or sharp objects before installation. Slightly inflate the inner tube to give it shape, insert it into the tyre, then fit the tyre onto the rim ensuring the tube is not pinched. Seat the tyre bead evenly around the rim and inflate gradually to the recommended pressure marked on the tyre sidewall, checking that the valve is seated straight and that the tube does not bulge or pinch. After inflation, spin the wheel and confirm even seating before use.

Recommendations

Use a pump compatible with Dunlop/Woods valves or an appropriate adapter. Always check tyre sidewall pressure recommendations and inspect the tube after installation for proper seating and possible leaks. Replace the tube if there are cuts, severe abrasions or repeated punctures.
