Given the increasing prevalence of electronic groupsets in modern road bikes, its often argued that the advantages they offer in terms of reliability, precision, and customizability outweigh the added cost and complexity. However, for those considering an electronic groupset conversion, a critical question remains: what are the actual power consumption and battery life implications of switching from a mechanical to an electronic groupset, and how do these factors impact the overall efficiency and practicality of the system, particularly for extended periods of use or in situations where recharging opportunities may be limited? Should we be prioritizing battery life and efficiency when selecting an electronic groupset, and if so, what specific features or technologies are most effective in minimizing power consumption while maintaining optimal performance?
