The Blackburn Mammoth CO2'fer Mini-Pump functions like any other high-volume hand pump for fixing flats on off-road tires, but inside the handle, a 16 g threaded CO2 cartridge is concealed allowing it to double as a CO2 inflator. Combine this easy interchangeability between pump and inflator with Blackburn's Anyvalve™ pump head, and the Mammoth CO2'fer becomes failsafe flat protection for both Presta and Schrader tire systems.
Maximum pressure is 50 PSI. Includes CO2 cartridge. Claimed weight is 191 g.
