Abstract: A suspension (1) for a bicycle (101) comprising an elastic element (2) and a blocking/releasing device (3) of the elastic element (2). The blocking/releasing device (3) comprises:—a closed hydraulic circuit (4) containing a working fluid (5);—a cylinder-piston assembly (60) comprising a cylinder (10) and a piston (6) slidable inside said cylinder, said cylinder-piston assembly (60) being inserted in the hydraulic circuit (4) and being operatively disposed in parallel with said elastic element;—a valve (8) commanded by an actuator (9) inserted in the hydraulic circuit (4) and configurable according to an open configuration, so that the working fluid (5) freely flows in the hydraulic circuit for enabling movements of the piston (6) inside the cylinder (10), and a closed configuration, so that the working fluid (5) is prevented from flowing in the hydraulic circuit (4) and the piston (6) is kept blocked by the working fluid (5);—a main housing (11) receiving inside the cylinder-piston assembly (60); wherein the hydraulic circuit (4) is made in a space formed between the walls of the main housing (11) and the walls of the cylinder (10).
