A bicycle saddle includes a shell fitted with fastening means for fastening the bicycle saddle to an associable bicycle, the shell extending, in a prevailing longitudinal direction (Y-Y), from a front end to a rear end, and a padding associated to an upper portion of the shell, opposite a frame of the associable bicycle. The shell has a rigid portion supporting the fastening means and a controlled deformation portion positioned between the rigid portion and the padding. The controlled deformation portion has at least one yielding insert adapted to deform elastically under compression during use.
