Simply attach it to your CO2 head, open the valve and pump! Eliminate CO2 range anxiety without having to carry a whole pump. If you use CO2, another pump head would be redundant. Capable of reaching 120+ psi, this is not the fastest pump, but a whole lot faster than walking. CO2 head required, not included. - Replace your spare CO2 Cartridge with a backup that never runs out - Same overall space as a CO2 Cartridge, and much lighter - Use your CO2 Head. No need to waste space and weight with a full pump - Compatible with Many Heads.

CO2 is great for fast, high pressure fill-ups, however, when you’re out, you’re out of luck! You can carry as many Cartridges as you think you need, now your last one can be endless. Same space as a cartridge, but lighter. CO2pump takes about the same space as a cartridge, but weighs only 35 grams. Unlike pumps, why waste space and weight to carry a pump head? Your CO2 Head is already a pump head with CO2pump. Although small, CO2pump is engineered to service high pressure. We designed a tiny pump with a compression ratio that enables you to reach 120psi without straining. With our design, smaller simply means more strokes, not a lack of pressure. Compatible with most brands of CO2 Heads*. Got a favorite CO2 Head? Already own one? CO2pump works great with most Heads. Simply attach the pump like a cartridge, open the valve and start pumping. *If your Head is a push-to-inflate head, you will need to hold the “push” action open while pumping.
