Abstract:
1. A bicycle damping assembly comprising: a damper tube having a first end portion, a second end portion and a side wall extending between said first end portion and said second end portion; a piston rod that carries a first piston, said first piston and said piston rod capable of telescopic movement with respect to said damper tube; a seal head that creates a seal between said first end portion of said damper tube and said piston rod; a reservoir chamber defined by said bicycle damping assembly; a fluid passage that extends between a compression chamber and said reservoir chamber; and a compression damping circuit that regulates compression fluid flow between said compression chamber and said reservoir chamber, said compression damping circuit comprising a pressure-activated valve including a partition and an acceleration-activated valve including an inertia mass; wherein said inertia mass is configured to slidably move relative to a reservoir shaft; wherein the inertia mass comprises an internal surface positioned adjacent to the reservoir shaft, said interior surface of the inertia mass being configured to contact an outer surface of the reservoir shaft; wherein said inertia mass comprises a main portion and at least one protective coating or layer, wherein said main portion of said inertia mass comprises brass, said at least one protective coating or layer being positioned directly along the interior surface of the inertia mass, wherein at least a portion of said at least one protective coating or layer is configured to contact said reservoir shaft; wherein a density of the protective coating or layer is greater than a density of the main portion, and wherein and a coefficient of friction of the protective coating or layer is greater than and a coefficient of friction of the main portion; and wherein said at least one protective coating or layer helps shield said main portion from contact with said reservoir shaft.
