What are the actual benefits of electronic groupsets in terms of shifting performance and reliability, and do they outweigh the added cost and complexity, particularly for riders who dont compete at a high level? Is the improved shifting speed and accuracy really noticeable in real-world riding, or is it more of a feature thats appreciated by pros and serious enthusiasts? How do electronic groupsets hold up in harsh weather conditions, such as heavy rain or extreme temperatures, and are they more prone to damage from crashes or other impacts? Can electronic groupsets be serviced and repaired by local bike shops, or do they require specialized tools and expertise? Are there any significant differences in terms of battery life and charging requirements between different electronic groupset systems, and how do these impact the overall user experience?
