PORTLAND DESIGN WORKS PUMPS/CO2 INFLATORS
When your bicycle features clean lines and eye-pleasing aesthetics, you don't want to ruin it with a drab plastic pump. The Portland Design Works Magic Flute is a mini pump/CO2 combo that's constructed from aluminum to keep weight down, and it's also polished for an attractive finish.
To use a cartridge, simply thread one into the head, install the pump, and then release the flow valve to fill the tire up. The valve helps prevent lost CO2 by controlling its discharge. The Portland Design Works Magic Flute comes with an alloy mounting bracket.
