## Long description

Inner Tube FISCHER Dunlop Valve 16" (ETRTO 47-305 / 50-305) length 40.60–40.64 cm is a spare bicycle tube designed for 16-inch wheels. Compatible with tires that follow ETRTO 47-305 and 50-305 dimensions, this inner tube features a Dunlop (Woods) valve and a nominal length of approximately 40.6 cm. It is intended for use on small bicycles, children's bikes and certain folding models where reliable air retention and straightforward installation are required.
Advantages
The tube is manufactured to fit common 16" ETRTO sizes, offering a close dimensional match for both 47-305 and 50-305 tires. The Dunlop valve facilitates inflation with common bicycle pumps and provides a secure seal when fitted correctly. The specified length ensures compatibility with rims and tire combinations that require a valve length near 40.6 cm, allowing for easier access and servicing. The construction provides airtight performance for everyday riding and routine repairs.
Suitable for
 Children's bicycles with 16" wheels
 Small adult folding bikes using 16" tires
 Replacement or repair of inner tubes in tires sized ETRTO 47-305
 Replacement or repair of inner tubes in tires sized ETRTO 50-305
Key specifications
 Wheel size compatibility: 16" (ETRTO 47-305 / 50-305)
 Valve type: Dunlop (Woods) valve
 Valve length: 40.60–40.64 cm (nominal)
 Intended use: bicycle inner tube for small wheels
 Air retention: designed for standard bicycle tire pressures appropriate to 16" tires
How to use
Remove the wheel from the bicycle and release remaining air from the damaged tube. Partially unseat the tire bead from the rim using tire levers, then remove the old inner tube by pulling the valve through the rim. Inspect the inside of the tire and rim strip for any debris or sharp objects. Slightly inflate the new FISCHER inner tube to give it shape, insert the valve through the rim hole, and place the tube inside the tire. Reseat the tire bead evenly around the rim, taking care not to pinch the tube, and inflate to the recommended pressure for the specific tire. Check the valve seating and perform a final inspection for proper fit and seal before reinstalling the wheel.
Usage recommendations
Use a pump compatible with Dunlop valves or an adapter when necessary. When replacing inner tubes, verify the tire ETRTO marking to ensure compatibility with 47-305 or 50-305 sizes. Avoid over-inflation beyond the tire's maximum pressure rating and routinely check for cuts or embedded debris that could cause repeated punctures.
