ROCKBROS HQ-75D-CO2 2-in-1 Mini Bike Pump & CO2 Inflator - Black

On a crisp morning ride, a sudden hiss from your tire can ruin the day—unless you have the ROCKBROS HQ-75D-CO2 in your saddle bag. This compact 2-in-1 tool combines a manual mini pump with a CO2 inflator, letting you handle punctures quickly and get back on the road or trail. Crafted from CNC machined aluminum alloy, it’s built to withstand the rigors of cycling while remaining lightweight and portable.

Key specifications

• Dual-mode operation: manual pumping or threaded 16g CO2 cartridge inflation (cartridges sold separately)
• Compatible with both Presta (FV) and Schrader (AV) valves via threaded connection
• Maximum manual pressure: 120 PSI (8.3 bar)
• Integrated dust cap protects the valve from dirt and debris

• Material: CNC machined aluminum alloy
• Color: Black
• Compact and lightweight design, ideal for on-the-go repairs

Why choose it

The ROCKBROS HQ-75D-CO2 eliminates the need to carry separate tools. Its dual-mode functionality means you can use the manual pump for gradual pressure adjustments or a CO2 cartridge for instant inflation in race conditions. The threaded connection ensures a secure, leak-free fit on both valve types, and the included bracket keeps the pump within easy reach on your frame.

Ideal use cases

• Road cycling: quick CO2 inflation for high-pressure tires
• Mountain biking: manual pumping for tubeless setups or trailside repairs
• Commuting: compact size fits in a backpack or pannier
• Touring: reliable backup for long-distance rides

Good to know

CO2 cartridges are not included; use standard threaded 16g cartridges. The pump does not have a built-in pressure gauge, so carry a separate gauge if precise pressure is critical. The aluminum alloy construction resists corrosion and wear, ensuring long-term durability.
