Câmara de ar para bicicleta FISCHER válvula Dunlop 27 polegadas (68,60 cm) — comprimento de válvula padrão para rodas de 27 polegadas

FISCHER inner tube with a Dunlop (Woods) valve, designed for 27" (68.60 cm) wheels. This inner tube fits tyres intended for 27-inch rims and is manufactured to provide reliable airtight sealing and compatibility with rims and pumps that accept a Dunlop valve. The tube is suitable as a direct replacement for worn or damaged inner tubes on road, city and leisure bicycles that require a Dunlop valve and the 27" size.

Advantages

The inner tube offers consistent air retention and straightforward installation thanks to its standardized shape and valve placement. A Dunlop valve ensures compatibility with many pump heads and rim types common on older or region-specific bicycles. The tube's dimensions match the 27" tyre circumference, enabling a proper fit and stable riding behavior when installed correctly.

Suitable for

• 27" road bicycles with tyres matching 27-inch specifications
• City and commuter bikes that use a Dunlop (Woods) valve
• Leisure and trekking bicycles for routine repairs and spare replacement
• Workshops and home kits for on-the-spot tyre repairs

Key specifications

• Wheel size compatibility: 27" (68.60 cm)
• Valve type: Dunlop (Woods) valve
• Valve length: standard length for 27" wheels
• Material: flexible rubber suitable for bicycle inner tubes
• Application: road, city, leisure bicycles

How to use

Inspect the tyre and rim for sharp objects or damage before fitting the inner tube. Partially inflate the new tube to give it shape, insert the valve through the rim hole and position the tube inside the tyre. Seat the tyre bead evenly around the rim and inflate gradually to the tyre manufacturer's recommended pressure, checking that the tube is not pinched and the valve is straight. After installation, perform a short test ride and recheck pressure to confirm proper sealing.

Recommendations

Use the inner tube as a like-for-like replacement for 27" tyres requiring a Dunlop valve. Keep spare inner tubes and a compatible pump in your repair kit, and always inspect tyre and rim condition before installation to reduce the risk of repeated punctures. Follow recommended inflation pressures for your specific tyre to ensure optimal performance and safety.
