Abstract
A bicycle frame set includes a main frame, a rear wheel suspension pivotally attached to the main frame, and a double eccentric cam assembly disposed within one or more pivot joints between the main frame and the rear wheel suspension. The double eccentric cam assembly includes inner and outer eccentric cams removably fastened together and retained in place within the pivot joint by a removable fastener passing through an aperture in the inner eccentric cam and defining a pivot axis. The aperture is eccentric relative to a perimeter of the inner eccentric cam. The inner cam is received within a correspondingly shaped opening in the outer cam which opening is itself eccentric relative to a perimeter of the outer eccentric cam. A rotational position of each of the cams is thus adjustable, so as to change a relative location of the pivot axis of the pivot joint.
