FISCHER CO2 Bike Pump with Cartridge and Universal Head for Schrader (AV) and Dunlop Valves – 1 Piece

The FISCHER CO2 Bike Pump with Cartridge and Universal Head is a compact emergency inflation kit designed for quick, tool-free tyre pressurisation. This single-piece kit includes a CO2 cartridge and a universal pump head that fits Schrader (AV) and Dunlop valves, enabling fast inflation for a wide range of urban and recreational bicycles. Its lightweight design makes it easy to carry on rides or store in a saddlebag for roadside repairs and race-stage support.

Advantages

The product provides rapid inflation using a CO2 cartridge, significantly reducing time spent fixing a flat compared with manual pumps. The universal head supports both Schrader (AV) and Dunlop valve types without adapters, simplifying use across multiple bike types. Its compact and lightweight construction offers convenient portability for commuting, training, or event support, while the straightforward, tool-free operation allows quick action during emergencies.

Suitable for

• Road bikes and city bikes with Schrader (AV) or Dunlop valves
• Commuters who need a compact emergency inflation solution
• Race support and quick on-route repairs
• Lightweight touring where carrying minimal gear is important

When it may not be suitable

This CO2 pump kit is intended for rapid temporary inflation and may not be ideal when precise pressure control or multiple successive inflations are required, as each cartridge provides a limited number of fills. It is not a replacement for a full-size hand pump when repeated use without additional cartridges is expected.

Key specifications

• Inflation method: single-use CO2 cartridge
• Valve compatibility: Schrader (AV) and Dunlop
• Included items: one CO2 cartridge and one universal pump head
• Weight: lightweight, designed for portability
• Use case: emergency and rapid on-the-go tyre inflation

How to use

Attach the universal pump head securely to the tyre valve (Schrader or Dunlop) and ensure a tight connection before activating the cartridge. Release CO2 according to the head’s control mechanism to inflate the tyre to the required pressure, monitoring inflation to avoid overfilling. After use, remove the spent cartridge and store the pump head in a protective bag or saddlepack. Follow safety precautions indicated on the cartridge regarding handling and storage of compressed gas.

What to consider before purchase

• Verify that your bike’s tyre valves are Schrader (AV) or Dunlop to ensure compatibility
• Consider how many inflations you may need and whether you should carry spare CO2 cartridges
• Ensure familiarity with safe handling and disposal of CO2 cartridges

Usage recommendations

Carry at least one spare CO2 cartridge if you frequently ride long distances or participate in events, and practice attaching and activating the pump in a safe environment before using it on the road.
