That is a good article. I looked to see if I could find followup articles which answered his opening question, "What is it that we are emulating?"(paraphrased) The short answer is cartridge suspension. A philosophical answer is we are trying to emulate money
. Money is what these discussions quickly devolve to. But that doesn't really advance our knowledge base.
I don't know how many suspension strokes per minute we experience on average. But if we had a dash light that blinked every time the forks or shocks changed direction ... it would essentially be constantly on.
Emulators give us an improvement, if you drill the flip'n holes. But what they do not provide is the cartridge chamber which separates the oil from the air. The older crowd will remember that ATF (automatic transmission fluid) was the best fork oil because it didn't "foam". Now, all fork oil is anti-foaming. However, none of it is foam-proof. Further, foam breeds more foam. You can carefully choose your viscosity but what happens to that viscosity when it becomes X% air?
Next up is the distinction between compression damping vs rebound. Think about what happen to the gills on a fish if you tow it backwards through the water. I can not understand why the emulator companies aren't making their units so that one side can be mounted "upside down". It might be as simple as that we have not demanded it.
Anyways, here is another link that if one reads through it twice, you will be the expert in any circle of friends.
