The ROCKBROS bike refill pump features a 160 PSI pressure gauge, making it easy and intuitive to read tire pressure. This allows monitoring of tire pressure at any time, preventing over-inflation.

Key features:

• Fast refilling: Thanks to the CNC-machined aluminum control button, you can precisely control the amount of CO₂ injected into the tire, with the ability to stop the refilling process at any time.
• Portable and lightweight: The pump weighs approximately 80g, with compact dimensions (6.1 x 3.6 x 3cm), ideal for placement in a backpack, pocket, or bike bag.
• Compatible with Presta and Schrader valves: The pump head is compatible with Presta and Schrader valves, featuring a special nozzle that easily converts.
• Ideal for refilling bike tires: Suitable for quick refilling of mountain bike, road bike, and mini bike tires.
• Compatible with all threaded CO₂ cartridges: Designed to accept all cartridge sizes (12g, 16g, 20g, and 25g). Includes an insulation sleeve (only for 16g cartridges).

Installation instructions:

1. Place the insulation sleeve over the CO₂ pump.
2. Tighten the pump until the metal needle pierces the cartridge.
3. Connect the head to the tire valve to prevent leaks.
4. Turn the cartridge half a turn and start refilling.

Note: After releasing the CO₂, the cartridge, head, and pump tip become very cold. To protect your hands, use the insulation sleeve and avoid direct contact with the CO₂ cartridges.
