322 is positioned such that it 39 s movement in chamber 326 is parallel and in the opposite direction from to the terrain induced force this positioning produces the greatest sensitivity from the inertial valve 322 because the entire terrain induced force vector is applied to the damper enhancement system in the exact opposite direction of the inertial valve 39 s 322 line of movement by contrast if the remote tube containing the inertial valve 322 were positioned at for example a 45 u00b0 angle from the position shown in fig5 the inertial valve 39 s 322 sensitivity would be decreased by approximately one half because only one half of the terrain induced force vector would be acting to move the damper enhancement system in the opposite direction of the valve 39 s line of motion thus twice the terrain induced force would be required to trigger the same response from the inertial valve 322 in this angled configuration thus in one embodiment of the damper enhancement system the angle of the remote tube 304 in which the inertial valve 322 resides is manually adjustable to change the inertial valve 322 sensitivity this embodiment may further include a sensitivity knob or dial for adjusting the angle of the remote tube 304 the sensitivity knob may have a range of different sensitivity levels disposed thereon for indicating the particular level of sensitivity to which the damper apparatus is set in one embodiment the sensitivity knob may be rotatably coupled to the bicycle frame separately from the remote tube and may be cooperatively mated with the remote tube e g with a set of gears numerous different.
