ABSTRACT:
A bicycle sprocket assembly includes a first sprocket, a second sprocket and at least one reinforcement member. The first sprocket includes a first main body and a first chain engagement portion. The second sprocket includes a second main body and a second chain engagement portion. The reinforcement member is coupled between the sprockets. Preferably, the reinforcement member is disposed in first and second apertures of the first and second sprockets at a radial location spaced radially outwardly of first and second inner end portions of the first and second sprockets. Preferably, a spacer is disposed between the first and second sprockets radially inwardly of the reinforcement member. The reinforcement member is preferably installable in the first and second apertures by a sliding movement generally perpendicular to a rotation axis of the first and second sprockets.
