A handle structure for sports equipment bars (B) particularly handlebars of cycles, motor cycles or the like. The structure (1) has a main tubular body (2) which defines a longitudinal axis (X), and has an outer surface (6) susceptible of being grasped by a user and an inner surface (7) designed to be operably mounted to the bar (B). A first device (3) axially locks the main body (2) to the bar (B). The tubular body (2) has a plurality of modular annular elements (10, 10′, 10″) designed for mutual coaxial connection along the longitudinal axis (X) for adjusting the overall length (L) of the body (2) to each user's needs. A sports implement incorporating such structure is also provided.
