A damper (100) comprising: a cartridge (102) comprising a compression damper (104) of a shock absorber, the compression damper comprising: a single adjustable fluid circuit configured for controlling a damping rate associated with multiple compression speeds of the shock absorber, wherein the single adjustable fluid circuit comprises: a fluid passageway (322) through a base valve (112); a positionally adjustable floating shim stack (218) positioned at one end of the fluid passageway (322), the positionally adjustable floating shim stack (218) configured for selectively blocking a flow of fluid through said fluid passageway wherein said positionally adjustable floating shim stack (218) comprises: a top surface; a bottom surface; a first end (332) that remains unclamped to any other component of the compression damper (104) during a compression of said shock absorber and, upon a position adjustment of the first end such that a first component (220) of the compression damper (104) comprises a pre-load hat (220) providing a first pre-load against said top surface at said first end (332), moves a distance into the fluid passageway (322); and a second end (314) that flexes upwards when said flow of fluid through the fluid passageway (322) pushes up against said bottom surface and overcomes a predetermined stiffness of the positionally adjustable floating shim stack (218) wherein the compression damper (104) further comprises a second component (312) providing a second pre-load against the top surface at the second end (314) during an upward flexing of the second end wherein a first portion of the pre-load hat presses against the positionally adjustable floating shim stack (218), and a second portion of the pre-load hat presses against the second component (312), thereby supporting the second pre-load being applied against the top surface at the second end (314) of the positionally adjustable floating shim stack (218) during an upward flexing of the second end.
