ABSTRACT:
A bicycle chain tension adjustment assembly includes a clamping member and a clamped member. The clamping member is attached to a rear bracket in which a rear shaft of a rear wheel hub of a bicycle is mounted, and has left and right ends and an inner annular wall with an annular cam surface of an adjustable dimension so as to be placed at tightening and loosening positions. The clamped member extends rightwardly of the right end of the rear shaft, and has a peripheral wall with an axis that is offset from the axis of the rear shaft to mate with the annular cam surface when the annular cam surface is in the tightening position.
