I have a nitrogen generator that I use to fill my car tires with compressed nitrogen. Before you guys get all wierd, I use compressed nitrogen for two reasons:
1) It doesnt contain moisture like compressed air, which can corrode rims
2) The pressure doesnt fluctuate with temperature as much as compressed air
I've seen the little compressed CO2 cartridges for filling bike tires, but CO2 pressure fluctuates a LOT with temp changes...moreso than regular compressed air. Have any of you seen small nitrogen containers for filling bike tires?
