FISCHER polkupyörän sisärengas Dunlop-venttiili 66,00 cm (26 tuumaa) ETRTO

FISCHER inner tube with a Dunlop (Woods) valve, designed for 26-inch wheels and sized to ETRTO specifications. The tube has a valve type commonly referred to as Dunlop or Woods and a length of 66.00 cm, making it compatible with many city, trekking and recreational bicycles that require a Dunlop valve. It replaces worn or damaged tubes to restore airtight performance and riding reliability on rims that accept 26" (ETRTO) tubes.

Advantages

The tube offers airtight sealing and simple installation on rims compatible with ETRTO 26-inch sizing. The Dunlop valve provides a sturdy connection for pumps and makes inflation straightforward. The construction is suitable for routine urban and leisure cycling needs and allows for quick field or workshop replacement when a tube has been punctured or aged.

Suitable for

• City bicycles with 26" wheels and Dunlop valve requirement
• Trekking and commuting bikes using ETRTO 26" inner tubes
• Recreational and leisure bicycles where a reliable spare tube is needed

Key specifications

• Valve type: Dunlop (Woods)
• Valve length: 66.00 cm
• Wheel size compatibility: 26 inch (ETRTO sizing)
• Intended use: inner tube for bicycle tyres

How to use

Remove the wheel from the bicycle, deflate and unseat the tyre beads to access the old tube. Inspect the tyre and rim for sharp objects or damage before installing the new tube. Slightly inflate the FISCHER inner tube to give it shape, position it inside the tyre, and carefully reseat the tyre beads onto the rim. Inflate to the manufacturer-recommended pressure for your tyre, checking that the valve sits straight and that the tyre bead is seated evenly around the rim. Reinstall the wheel and perform a brief safety check before riding.

Recommendations

Check tyre and rim condition prior to installation, use the tyre manufacturer's recommended inflation pressure, and ensure the valve is tightened and aligned to prevent leakage or damage during inflation. Carry a compatible spare tube and a pump suitable for Dunlop valves for safe roadside repairs.
