Blackburn Mammoth C02'Fer Mini Pump

If you're the type of person who can only sometimes find a spare CO2 cartridge when you need it on the trail, Blackburn's Mammoth C02'Fer Mini Pump will work with your seat of the pants style perfectly. The mini pump is not only compatible with Presta, Schrader, and Dunlop valves, but it can also double as a threaded CO2 cartridge inflator and includes one spare cartridge. Blackburn designed the pump to actually hold the CO2 cartridge inside of it, eliminating the need to empty pockets and packs on the side of the trail the next time you find yourself with a flat.
