Blackburn Mammoth CO2’fer mega pump
Works as a regular pump. Can hold a CO2 cartridge and can be a CO2 pump. Instead it can hold a modified tool bar. Fits Schrader or Presta.
Grit has snuck in so the shaft is a little marked but that doesn’t make a difference to air flow as different seal below. Really well built and can be taken apart for cleaning and service. I’ve just cleaned and lubed it.
Cool bit of kit
