A rear wheel suspension system pivotably attached to a bicycle. The suspension system has an upper link attached to a main frame at a first pivot point, and a rear stay member attached to the upper link at a second pivot point. A lower link is attached to the main frame at a third pivot point, and is pivotably attached to the rear stay member at a fourth pivot point. A shock absorber is pivotably connected to the upper link and to the main frame. An instantaneous center of rotation (ICR) is defined where an upper axis extending through the first and second pivots intersects a lower axis extending through the third and fourth pivots. The ICR displaces along a trajectory from behind the bottom bracket, through an inflection point at which the upper axis and the lower axis are parallel, to in front of the bottom bracket, as the shock absorber compresses.

A spacer for positioning between a head tube of a bicycle frame and a front wheel fork of the bicycle. The spacer includes an annular body defines a center axis and extends axially between annular upper and lower spacer surfaces. A bore extends axially through the body concentrically with the center axis between a first opening in the annular upper spacer surface and a second opening in the annular lower spacer surface. The annular upper spacer surface includes a radially outer planar rim and an engagement flange disposed radially inwardly from the planar rim, the engagement flange projecting axially upwardly from the planar rim and circumscribing the opening. The planar rim and the engagement flange abut complementary surfaces on a lower mating surface of the head tube and form a seal with the head tube upon being engaged therewith.
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.
A composite bicycle frame which comprises of a main frame including interconnected tubes and substantially composed of a composite material and having a composite layup structure. At least one electric wire electrically interconnects electrical components mounted to or in the frame. The at least one electric wire is embedded in the composite material structure forming the composite main frame. The electric wire has connectable conductive ends at each of the opposed ends thereof.
A bicycle rear wheel suspension system includes an upper link and a lower link both pivotally attached to the frame and to a rear stay member. An instantaneous center of rotation of the rear stay member is defined at an intersection between an upper axis extending through first and second pivots of the upper link and a lower axis extending through third and fourth pivots of the lower link. Throughout a travel distance of a shock absorber of the suspension system, the instantaneous center of rotation remains below an average chain torque line of the bicycle, the lower axis remains above an axle axis extending through the rear wheel axle, and a portion of the lower axis defined between the third and fourth pivots extends below the average chain torque line.
