I have a
Lezyne Shock Digital Drive, basically a floor pump for your shock. Its great to fill a shock/fork after a rebuild, the digital gauge is accurate, and it has a valve with a bleed button, and an isolation valve to separate the air in the hose from the shock, it makes removal easy. Negative is it only goes to 300psi if you need a high pressure (350psi) pump.
I also have a
Leyzne Digital Shock Drive in my travel tool box. Its small enough to carry in a hip bag or backpack if you're doing suspension fine tuning on the trail. It's really accurate/consistent, and has a simple digital readout. Some complain it needs a battery, but it will blink low battery for 2 months before it actually dies. I have spare batteries on the parts wall. (goes to 350psi)
I aslo have a
Topeak PocketShock DXG. Analog readout, valve that isolates the shock from the hose, simple and strong. I'm going to buy the
XL version of this pump for the garage and use the smaller one for trail head/car. In the garage it can be a little longer and does not need to be so compact.
To me the valve that isolates the hose from the shock is important feature. This type of connector eliminates air loss when disconnecting the hose. You pump the fork to 102psi, isolate the hose from the shock valve, release the pressure from the hose, and then remove the valve from the shock, this way exactly 102psi stays in your fork.
The one way valves puts a combined 102psi in the fork and in the pump hose, and when you unscrew a pressurized hose a few psi are lost from the combined hose and fork psi.
Thats my take on shock pumps.
