Bomba de bicicleta FISCHER Cabezal doble Plástico — para todas las válvulas, cabezal de resorte

The FISCHER Duokopf Plastic bicycle pump is a compact, lightweight inflator designed for use with all common valve types. Its plastic barrel and dual-head (Duokopf) configuration accommodate both Presta and Schrader valves without the need for adapters. A spring-loaded head secures the connection to the valve, simplifying attachment and reducing air loss during pumping. This pump is intended for routine tire inflation at home and for quick repairs while out riding.

Advantages

The Duokopf Plastic pump combines a minimal weight and small footprint with universal valve compatibility, enabling straightforward use on different bikes and tire types. The plastic construction keeps the unit affordable while providing adequate durability for occasional and everyday use. The spring-loaded head offers a stable connection to the valve, making pumping more efficient and reducing the risk of the head slipping off during use.

Suitable for

• Inflating bicycle tires with Presta (French) valves
• Inflating bicycle tires with Schrader (car) valves
• Home maintenance and routine tire pressure adjustments
• Portable repair kits for rides and short trips

Key specifications

• Material: plastic barrel and handle
• Head type: dual-head (Duokopf) for universal valve compatibility
• Head mechanism: spring-loaded attachment for secure fit
• Design: compact and lightweight for portability
• Intended use: manual hand pump for bicycle tires

How to use

Place the pump on a stable surface or hold it firmly with one hand. Select the appropriate side of the dual head for the valve type in use, then press the head onto the valve stem until the spring mechanism engages and the connection feels secure. Operate the pump by moving the handle in steady strokes to inflate the tire to the desired pressure. After inflating, carefully release the head from the valve by lifting or pressing the release mechanism, ensuring minimal air loss.

Recommendations

Check the recommended tire pressure printed on the tire sidewall and avoid exceeding this value. Inspect the pump head and valve for dirt or damage before use. Store the pump in a dry place and avoid prolonged exposure to direct sunlight to preserve plastic components. For frequent or high-pressure use, consider a pump with a metal barrel or a dedicated floor pump for improved durability and faster inflation.
