Whats the point of pouring thousands of dollars into an electronic groupset if the battery life is going to be a major concern, and how do reviewers not factor in the added weight and bulk of the batteries when comparing the supposed efficiency of these systems, and isnt it just a marketing gimmick to get people to upgrade their entire drivetrain when a simple mechanical setup would suffice, and what are the actual benefits of electronic shifting that would make it worth the hassle and expense, and how do you even define reliability when it comes to electronic components that are prone to failure and require complex troubleshooting, and can someone explain to me why the reviews of these systems always seem to focus on the smoothness of the shifting but never seem to mention the actual mechanical advantage of the system, and isnt it just a fact that electronic groupsets are only as good as the weakest link in the chain, which is usually the battery or the wiring, and how do you account for the environmental impact of all these disposable batteries and the e-waste generated by these systems, and whats the real-world difference between a $2,000 electronic groupset and a $200 mechanical one, and arent we just getting ripped off by the bike industrys latest fad.
