If you look at the physical mechanics of a Schrader valve, you will notice that it has a bit of movement that neither lets out air or lets it in as you depress the valve. That means when you are screwing off your pump, the valve fully closes just before you hear the air escape from the pressurized pump. Try it sometime and you will see.

You only loose air when you install the pump, not on removal. When you remove the pump the air you hear release is only whats left over in the pump...

Most of what you are hearing is air that is left in the pump, won't argue that, but you do also loose a bit from the shock as well.

My rear shock is kinda dirty, so during unscrewing of the pump, I'll loose a bit, so I compensate and pump more. But with my new purchase, no issues. It's different per person.

my shock pump has a special peice that screws and unscrew on that allows me to loose no air

Thanks,.. Didn't think when setting up my D.H. ride that it should be angled,. now I know why the front end dives so much.. great tip!!!

Been playing to shock pump game with my 4XXXX recently. 5 pounds of pressure and 2mm of stroke makes a HUGE difference with only 4 inches of travel...

my DHX 5.0 loses air after a few rides. I put in 200 psi and two days later I checked it had 75psi. What should I do get a rebuild to replace seals or what.

it could be blown, i would take it in to a bike mechanic if you do not know how to do it your self. you may need to purchase new seals etc. which are pretty cheap.
