ThePubSA Posted November 5, 2013 Share Hey hubsterz Need a new shock pump.The giant one i have releases air pressure as you disconnect it,so can never get a propper setting and is becoming a pain. Need you huberz to point me towards a decent quality ,cheapish shock pump that will retain the desired psi once disconnected. Ty in advance Link to comment Share on other sites More sharing options...
patches Posted November 5, 2013 Share I may be wrong, but it was once explained to me that the air that releases when one disconnects the shock pump is the air in the shock pump hose. So therefore it does not affect the pressure in the shock itself. But if you reconnect it, your pressure reading WILL be less than what you pump it to previously, as aid once again goes into the hose and pump chamber, thus creating a bigger volume and lower pressure. So there's a good chance your shock pump is fine. Helpmytrap, Grebel and Gunzo 3 Link to comment Share on other sites More sharing options...

HOEKVLAG Posted November 5, 2013 Share Was explained to me in exactly the same way. Don't know about the calibration of different shock pumps though... Link to comment Share on other sites More sharing options...

Mine does have the like dump valve where you can just dump as much out and still get the reading.Must be one with a 1 way valve for something >?

droo Posted November 5, 2013 Share If you're looking for reliable and simple, Rockshox make one that retails around R 400. Very thin barrel so gets to high pressures with little effort (but can take a while), and the chuck has a decent check valve which stops the air escaping. Lezyne Shock Drive gets my vote for being awesome looking though. About the same price too. Link to comment Share on other sites More sharing options...
droo Posted November 5, 2013 Share Although what the rest of the crew have said is true - there will always be a bit of air that escapes. Use the pressure reading before you disconnect the pump as the benchmark, it's the closest to the actual pressure inside the air chamber once disconnected. Also, if you keep the same benchmark it doesn't really matter what the actual pressure inside is unless you're using a bunch of different pumps to inflate your shock.

ThePubSA Posted November 5, 2013 Share I almost have to speed turn mine off the reverb,which is hard with huge fingers in a 30.9 tube.Will get diff air left in depending on how fast i turn it off,almost like 2 seperate sounds one of the pipe releasing air and then the valve ?

droo Posted November 5, 2013 Share Hmmm. Then it sounds as though your first thought about the check valve being past it may be true... in which case my first post stands. I'd probably recommend the RS one then, because I use it in the shop and the chuck works well. The Lezyne should work great too, I just haven't used it as much yet.

mikeonthetown Posted November 5, 2013 Share Its such a tiny amount of air i would presume, shouldn't make much of a difference if any. Link to comment Share on other sites More sharing options...
