Blackburn Mammoth Co2'Fer

No retail packaging.

Mini-Pump and Co2 in one.

This cleverly designed and fully functional mini-pump functions as a standard mini pump AND allows a CO2 cartridge to stow away inside and can be quickly rearranged as a CO2 inflator. The head conveniently morphs into a thread-on CO2 inflator.

Presta and Schrader valve compatible. Rubber insert on valve head must be reversed to switch between valve types.
