Abstract
A control device, for the rear shock absorber of a bicycle, includes a first air chamber, a second air chamber, a third air chamber, an auxiliary air chamber, and a sliding rod. An air piston is arranged inside one of the first, second and third air chambers. However, those air chambers are respectively provided with an air hole communicating with the auxiliary air chamber. The sliding rod is configured with air tight rings, which are arranged top-to-bottom and tightly touch the inner wall of the auxiliary air chamber. Moreover, the sliding rod is provided with grooves between the air tight rings, so that the axially movement of the sliding rod may manage the first, second and third air chambers to be disconnected or to communicate with one other via the grooves to adjust the damping coefficient of the rear shock absorber.
