## Summary description

FISCHER bicycle inner tube with Dunlop (Sclaverand/Presta-compatible) valve, length 45.70 cm, designed for 18-inch wheels according to ETRTO standards. Suitable for replacing worn or damaged tubes on compatible 18" bikes, it provides a secure air seal and straightforward installation. Use for commuter, folding or small-wheel bicycles where this valve and size fit.

## Long description

FISCHER inner tube for 18" wheels features a Dunlop-style valve compatible with Presta-type pumps and a tube length of 45.70 cm suitable for ETRTO-specified 18-inch bicycle rims. This replacement tube is designed to restore airtight performance and reliable inflation on commuter, folding and small-wheel bicycles that accept this valve type and size. The construction delivers a smooth fit inside standard 18" tires and supports routine maintenance or emergency repairs.
Advantages
The tube provides a secure air seal and is compatible with pumps that work with Dunlop/Presta-style valves. Its specified length ensures correct valve reach through most 18" rim holes, reducing the need for extenders. Made to fit ETRTO 18-inch tire dimensions, the design simplifies installation and replacement while maintaining a compact, lightweight profile suitable for small-wheel bicycles and folding models.
Suitable for
 Replacement of worn or punctured inner tubes on 18" (ETRTO) bicycles
 Commuter and city bikes with small wheels
 Folding bicycles and children's bikes that accept Dunlop/Presta-style valves
 Carrying as a spare for long rides or urban cycling
Key specifications
 Valve type: Dunlop-style (compatible with Presta-compatible pump heads)
 Valve length: 45.70 cm
 Wheel/tire size compatibility: 18" (ETRTO standard)
 Material: standard butyl rubber inner tube
 Weight profile: lightweight, suitable for small-wheel applications
How to use
Deflate the damaged tube completely and remove the wheel from the bicycle according to the manufacturer's instructions. Unseat the tire beads and extract the old tube, inspect the tire and rim strip for sharp objects, then insert the new FISCHER inner tube. Position the valve through the rim hole, ensure the tube sits evenly inside the tire, reseat the tire beads and partially inflate to check alignment before fully inflating to the recommended pressure printed on the tire sidewall. Check the valve for secure seating and test-ride the bicycle to confirm proper installation.
Usage recommendations
Maintain recommended tire pressure as indicated on the tire sidewall, avoid overinflation, and carry a basic repair kit when riding. Verify compatibility of valve length and rim valve hole before purchase; consider a valve extender if your rim or accessories require greater valve reach.
