What I don't understand is how one side has the spring while the other
side (the right one, if you're sitting in [that's right, "in"] the
bike) has the air dampening. So that means that only the left side is
absorbing any road shock!

I didn't think so -- thanks for the suggestion, it never occured to me
that maybe my quick-release axle (or whatever that thinggy is called)
is at fault!

Hehe...my up-front demonstrator bike would be my own -- but you're
right about my mechanical ineptitude, as well as lack of business
acumen! Still, I was only wondering about "kick-backs" to the company
and so forth....

I'm not sure where you got that idea from. AFAICT each side of the fork
has identical spring/elastomer setup, spring at the top (so it can be
adjusted at the fork crown end) and elastomer underneath. The air
damping is within the elastomer as closed cells in the material.

Um, it says so in the manual, don't it? Also, the dampening can only
be controlled on the right side, while the "resistance" (I forget the
technical term) can only be adjusted on the left side.

I've got the upgraded fork, BTW, the one with the air dampening on the
right and spring coil "resistance," as I say, on the left.

Fair enough, I'm just looking at the web site pic and that may well be
the old Ballistic fork on mine.

However, both sides will affect the behaviour of the fork because any
shock they take through the wheel should be transmitted through both sides.

I just wonder how shock is transmitted evenly through both sides when
only one side has actually got the spring suspension while the other's
got an hydraulic dampening cartridge (??).
