Whats the real consensus on mini pumps vs. CO2 cartridges for on-the-go tire inflation - are mini pumps a necessary evil or a waste of space on a modern bikes seat post? Do the benefits of always having a reliable source of air outweigh the added bulk, or are CO2 cartridges and a pump at home good enough for most riders?
Is the notion that a good mini pump can inflate a completely flat tire in under 100 strokes just a myth perpetuated by manufacturers, or are there actually pumps out there that can deliver on this promise? What features should I be looking for in a mini pump to ensure it can handle the demands of regular commuting or long-distance touring - any particular materials, valve types, or ergonomic designs that are more effective than others?
