speaking of upper body...
you should see me pump up the tires to 120 psi on my bike, at around 110 psi, my feet are off the floor, and it is taking my WHOLE weight on the pump, fiance always has a good laugh:D
reached to the way back for this topic!
I just got a new floor pump and MAN is it hard to get it off the valves! It's a Serfa pump with dual heads. I tried it on my presta and schreader valves and have the same problem. I flip the switch (yes, in the proper direction!) to release and have to tug and tug before it comes off the valve. I also noticed that it is really hard to get it on the presta properly, so that the air guage registers. Am I just a pump dork or should I return the pump?
I also noticed that I feel no pump pressure until the handle is all but 3-5 inches from being pushed in all the way.
