Cycling biomechanics are critical for optimizing performance and preventing injury. This study investigates how saddle height (SH) adjustments affect hip and knee joint angles in cycling, with implications for performance and injury prevention. The primary goal is to quantify changes in joint angles during the pedal stroke based on SH variations. A secondary aim is to assess the consistency of these changes across different body types and their impact on cycling efficiency and injury risk. Thirteen cyclists (7 female, 6 male) participated in biomechanical assessments on a stationary bike, with measurements taken at their preferred SH and a formula-based SH. Joint angles at the hip and knee were recorded during a full pedal stroke under both conditions. Preliminary results show that formula-based SH adjustments reduced knee extension angles (left: 6.34°, right: 8.04°) compared to the preferred SH. This suggests altered lower-limb mechanics that could affect cycling efficiency and joint loading. These findings emphasize the importance of precise SH adjustments in optimizing bike fitting, enhancing performance, and minimizing injury risks across diverse body types.
