Assignee:

Specialized Bicycle Components, Inc. - Morgan Hill CA

International Classification:

B62K 2528

US Classification:

280284

Abstract:

A bicycle including a frame having a main frame portion and an articulating frame portion pivotally mounted to the main frame portion and carrying a rear wheel of the bicycle at a hub axis. A shock absorber is operably connected between the main frame portion and the articulating frame portion to provide resistance to articulating motion of the articulating frame portion. A rearward end of the shock absorber preferably is pivotally mounted to the articulating frame portion at a location near the hub axis. The shock absorber preferably is positioned within a perimeter defined in a vertical plane generally by the articulating frame portion.

Assignee:

Specialized Bicycle Components, Inc. - Morgan Hill CA

International Classification:

B62K025/28

US Classification:

280284

Abstract:

A bicycle frame assembly having a main frame and an articulating frame supported for movement relative to the main frame. The articulating frame is configured to carry a rear wheel for rotation about a hub axis. A shock absorber is operably connected between the main frame and the articulating frame to provide resistance to articulating motion of the articulating frame. The articulating frame includes a chain stay member and a shock support member fixed for angular displacement with the chain stay member.

Specialized Bicycle Components, Inc. - Morgan Hill CA

International Classification:

B62K019/00

US Classification:

2802811, 280283

Abstract:

A bicycle including a frame having a main frame portion and an articulating frame portion pivotally mounted to the main frame portion and carrying a rear wheel of the bicycle. A shock absorber preferably is operably connected between the main frame portion and the articulating frame portion. Preferably, the top tube and down tube of the main frame contact one another for a distance extending rearwardly from the head tube of the main frame. In one arrangement, the down tube has a non-circular cross-sectional shape.

International Classification:

F16H 61/00

US Classification:

474 80

Abstract:

A bicycle rear derailleur guard assembly for use with a bicycle having a derailleur mounted to a frame of the bicycle by a derailleur mounting bolt. The derailleur guard assembly preferably includes a body supportable by an axle assembly of the bicycle. The body is configured to extend from an axis of the axle assembly to a space adjacent the mounting bolt of the derailleur and defines an inner surface facing the frame when the guard assembly is mounted to the bicycle. A support is configured to support the derailleur when the guard assembly is mounted to the bicycle and, in at least one arrangement, the body is positioned outwardly of the derailleur mounting bolt within the space adjacent the mounting bolt.

Assignee:

Specialized Bicycle Componets, Inc. - Morgan Hill CA

International Classification:

B62K 1/00

US Classification:

280279, 280276

Abstract:

A head tube for a bicycle frame that accommodates oversized frame tubing and the use of a standard sized head set. Preferably, the head tube includes a body defining a pair of lateral extensions that cooperate with the body to define an outer surface configured to receive at least a portion of a frame tube. In addition, preferably, the head tube defines a wall thickness that is thicker at the bottom of the head tube than the thickness at the top of the head tube. In addition, preferably, the wall thickness is greater at both of the top and the bottom of the head tube than the wall thickness of the middle of the head tube. Preferably, in at least a portion of the head tube, the wall thickness is thicker in a forward side than the thickness in a rearward side.

Assignee:

Specialized Bicycle Components, Inc. - Morgan Hill CA

International Classification:

B62K 25/10

US Classification:

280284

Abstract:

A frame assembly for a bicycle having a front wheel and a rear wheel. The frame assembly preferably includes a main frame and a sub-frame, which is movable relative to the main frame and configured to carry the rear wheel. A shock absorber extends between and is connected to the main frame and the sub-frame. The main frame includes a down tube and a monolithic bottom bracket support. The monolithic bottom bracket support is connected to a rearward end of the down tube and preferably includes an opening configured to support a pedal crank assembly for rotation about a crank axis. Preferably, the shock absorber is connected to the main frame for rotation about a pivot axis positioned forward of the opening of the bottom bracket support. Desirably, the shock absorber pivot axis is positioned forward of a line passing through the crank axis and a center point of the down tube at the junction of the down tube and the head tube. In one arrangement, the monolithic bottom bracket support surrounds a portion of the shock absorber.
