## Long description

The Inner Tube FISCHER Dunlop Valve 45.70 cm for 18-inch Wheels (ETRTO) is a spare bicycle inner tube designed to fit 18-inch wheels following ETRTO sizing. It features a Dunlop (woods) valve and a tube length of 45.70 cm, intended for use in children’s bicycles, folding bikes and other small-wheeled cycles where ETRTO 18-inch sizing is specified. The tube provides an airtight seal when paired with a correctly sized tyre and rim, enabling straightforward repairs or replacements.
Advantages
This FISCHER inner tube offers compatibility with 18-inch ETRTO systems and a Dunlop valve for easy inflation with appropriate pumps or adaptors. The specified length ensures correct fit on rims and inside tyres designed for small wheels, and the tube’s construction aims to maintain air retention and withstand typical riding stresses. The product is suitable for quick replacement during routine maintenance or roadside repairs.
Suitable for
Children’s bicycles with 18-inch wheels
Folding bikes that use 18-inch ETRTO tyres
Small-wheeled city or commuter bicycles
On-the-spot tube repair or replacement
Key specifications
Valve type: Dunlop (woods) valve
Tube length: 45.70 cm
Wheel compatibility: 18-inch (ETRTO) tyres and rims
Material: butyl rubber (standard for bicycle inner tubes)
Use: replacement inner tube for small-wheeled bicycles
How to use
Inspect the tyre and rim for sharp objects or damage before installation. Slightly inflate the tube to give it shape, then insert the valve through the rim hole and seat the tube evenly inside the tyre. Work the tyre bead over the rim, taking care not to pinch the tube. Inflate the tube to the tyre manufacturer’s recommended pressure, checking that the tyre bead is seated correctly around the rim. Recheck for leaks and ensure the valve is secure before riding.
Usage recommendations
Match the inner tube to the tyre’s ETRTO size and recommended pressure range. Use a valve-compatible pump or an adaptor for Dunlop valves if required. Replace the tube if previous puncture repairs are near the valve or if the tube shows signs of deterioration. Carry a spare tube and basic repair tools when riding small-wheeled bicycles for quicker roadside fixes.
