CO₂ Pump Head RockBros aluminium valve head compatible with Presta and Schrader — black

The CO₂ Pump Head RockBros aluminium valve head is a compact accessory for rapid tyre inflation using disposable CO₂ cartridges. Machined from aluminium alloy and finished in black, this pump head accepts both Presta and Schrader valves and is designed to attach to standard threaded CO₂ cartridges (cartridge not included). It is intended for use on road, gravel and commuter bicycles where fast, portable inflation is needed after a puncture or when adjusting tyre pressure on the go.

Advantages

This aluminium valve head provides a lightweight and durable connection between the CO₂ cartridge and the tyre valve. Dual compatibility with Presta and Schrader valves eliminates the need for additional adapters and simplifies on-bike repairs. The metal construction offers better wear resistance and a secure threaded fit to standard cartridges, enabling quick inflation with minimal effort.

Suitable for

• Road bicycles requiring fast tyre inflation during rides
• Gravel bikes used on mixed surfaces where punctures are possible
• Commuter bikes for quick roadside pressure adjustments
• Cyclists who carry CO₂ cartridges for emergency tyre inflation

When it may not be suitable

This valve head is not a complete pump; it requires a compatible CO₂ cartridge to inflate a tyre and is supplied without one. It is not intended for use as a substitute for a manual pump when precise, gradual pressure adjustments are needed or when multiple sequential inflations are required without additional cartridges.

Key specifications

• Material: aluminium alloy
• Valve compatibility: Presta and Schrader
• Colour: black finish
• Attachment: threaded connection to standard CO₂ cartridges (cartridge not included)
• Intended use: portable CO₂ inflation for bicycle tyres

How to use

Thread the pump head onto a compatible CO₂ cartridge by hand until secure. Position the head over the tyre valve—ensure the valve type is correctly seated for either Presta or Schrader—and open the cartridge release according to the head and cartridge design to allow CO₂ flow into the tyre. After inflation, close or remove the cartridge following safe handling practices, and check tyre pressure before riding. Follow any safety instructions supplied with the CO₂ cartridge.

What to consider before purchase

• CO₂ cartridges are not included; purchase compatible threaded cartridges separately.
• Consider carrying a pressure gauge or using a tyre with recommended pressure markings for safe inflation.
• Confirm compatibility with the threads of common disposable CO₂ cartridges you plan to use.

Usage recommendations

Use this RockBros CO₂ valve head for emergency roadside inflation. Handle cartridges with care: avoid exposing them to heat, and follow cartridge manufacturer instructions. For multiple inflations, carry additional cartridges or a backup manual pump to ensure you can complete your ride.
