Product Information

Full details

The Silca EOLO IV CO2 Regulator is designed for cyclists who prioritize weight and precision during emergency roadside repairs. This compact, all-metal inflator allows for controlled, gradual CO2 release, making it ideal for both seating tubeless tires and topping off pressure in inner tubes. While it provides unparalleled portability, users must be comfortable handling CO2 cartridges manually since the device lacks an insulated sleeve.

FAQs

Does this work with unthreaded CO2 cartridges?

No, the Silca EOLO IV requires threaded CO2 cartridges for a secure connection.

Can I reuse a partially empty cartridge?

Yes, because the EOLO IV has a flow-control dial, you can close it to save remaining gas for later.

Will this work on a mountain bike?

Yes, it is compatible with both Presta and Schrader valves, making it suitable for mountain, road, and gravel bikes.

How do I avoid freezing my hand?

Since the metal body gets very cold, it is recommended to hold the inflator by the dial or use a glove when discharging the cartridge.

Is any maintenance required?

Keep the internal threads clean of dirt and ensure the rubber seals are not cracked or damaged.

Troubleshooting

Air is leaking between the cartridge and the regulator

Ensure the CO2 cartridge is fully and tightly threaded into the regulator head.

The inflator is difficult to turn

Check for debris in the threads and ensure the O-ring is seated correctly.

Setup, Compatibility & Care

To use the EOLO IV, follow these steps:

  1. Ensure the turn dial is in the closed position.
  2. Thread your CO2 cartridge into the head until it is secure.
  3. Attach the head to your bike valve (press on for Presta, thread on for Schrader).
  4. Slowly rotate the dial to initiate airflow.

Compatibility: The device works with all standard threaded CO2 cartridges. It is compatible with Presta and Schrader valves.

Care: Since the unit is made of metal, keep it free of grit and debris. Occasionally wipe the threads with a clean cloth to ensure the dial continues to rotate smoothly. Store in a dry place to prevent corrosion.
