Whats the point of even carrying a mini pump if its just going to be a mediocre, space-saving compromise thats only there to make you feel better about being woefully unprepared for a real mechanical issue? Are we really that obsessed with shaving grams that were willing to sacrifice actual functionality? When selecting a mini pump, shouldnt the key factors be its ability to actually inflate a tire to a reasonable pressure, rather than just its size and weight? Whats the minimum pressure and volume that a mini pump should be able to deliver in order to be considered even remotely useful? And why do so many manufacturers seem to think that 60-80 psi is sufficient for a road bike, when we all know thats not even enough to get you out of a parking lot, let alone up a real climb?
