Claim:
A bicycle frame, comprising: a substantially rigid front triangle including a bottom bracket shell and a head tube for holding a front wheel via a fork; a substantially rigid rear triangle for holding a rear wheel; a top linkage pivotally connected to the front triangle at a top-front pivot axis and pivotally connected to the rear triangle at a top-rear pivot axis; and a bottom linkage pivotally connected to the front triangle at a bottom-front pivot axis and pivotally connected to the rear triangle at a bottom-rear pivot axis; the top-front, top-rear, bottom-front, and bottom-rear pivot axes positioned such that at 0% suspension compression, a line extending from the top-rear pivot axis through the top-front pivot axis intersects a line extending from the bottom-rear pivot axis through the bottom-front pivot axis at a focus that is located in a space bounded by: a front line that is an axis of the head tube, a bottom line extending horizontally from an axis of the bottom bracket shell, a top line 130 mm above and parallel to the bottom line, and a rear line that is perpendicular to the bottom line and the top line and 200 mm in front of an axis of the bottom bracket shell.
