ABSTRACT: This paper provides an overview of recent advancements in the field of bicycle fitting, focusing on the balance between aerodynamic advantages and physical performance. The importance of achieving optimal bicycle rider positioning is emphasized, particularly in enhancing performance and preventing pathology. The historical evolution of bicycle fitting methods, from subjective preferences to evidence-based approaches, is discussed, along with the role of technology in facilitating biomechanical analysis and simulation. The paper introduces a computational methodology (IPS IMMA software) for fitting a racing faired recumbent bicycle, emphasizing the need to integrate biomechanics and aerodynamics considerations. By aligning rider posture with biomechanical recommendations and minimizing encumbrance, the proposed methodology aims to enhance both aerodynamic efficiency and rider comfort. The article concludes with a presentation of methods and results, highlighting trends and ranges of motion during the pedalling cycle. Gender-based differences in joint angles are highlighted, thus underscoring the need for tailored fitting approaches.
