There are lots of skills that aren’t worth having because there are better ways of accomplishing the same goal that are easier. I have owned and used Zefal pumps. I
know how to pump up a tire with one. I just choose to use an easier, less difficult method.
As to leaking hoses, hasn’t been a problem in 20 years of using one. Zefals, on the other hand, don’t work at all if you run over them…which I have done numerous times.
As well, you can exert more force on the air column in the pump with it held between your hands than you can pushing down on the ground.
Um…no. Physics. When you push down into the ground, the maximum force is your body weight. When you push from one arm into the other, you can’t exert as much force. We don’t hold floor pumps between our hands and pump tires that way because we can exert as much force as our body weight.
