Cheez1ts,
I think what you had setup work for you. The comment I made is not without
merit or understanding. Reducing sag affects the ability of the wheel to
follow the ground. Load change at the wheel become more abrupt and traction
and weight balance is affected. An example, after you hit bump and shock is on
the rebound stroke the wheel will track down the back side of the bump if
there is enough sag (droop travel). If there is not enough sag then the wheel
will drop down to bottom of the next bump while losing contact to the ground
at the same time. The wheel that is following the ground will load up the
suspension more smoothly and maintain excellent tracking and traction. The
wheel that loses contact with the ground will transfer weight to other wheel
(the weight balance will move to the other wheel unless you compensated). When
the wheel does make contact the suspension will load more abruptly which
reduces tracking and traction. The flip side of this at 15% sage both sides is
you gain 1.05” of the rear and 0.45” front vertical over a conventional setup
f 20: r30 sag. Bottom line, the ability for the rider to compensate for these
changes is much bigger part then the suspension itself. Generally, the
smoother things are and the less rider compensation the faster one will be but
that is debunked all the time and why it can be difficult to tune MTB
suspension. FYI, adding more spring preload to the spring by reducing sag or
increasing damping does not increase stiffness in any way. It does increase
the load to move the spring and damping only changes the rate of load. If some
tell you other then ask why.
