While I appreciate the poetic sentiment, let's not romanticize the perils of mechanical systems. Yes, a flat battery can be disastrous, but so can a poorly maintained derailleur. Both systems require vigilance, albeit in different forms.
Mechanical systems may offer a tactile satisfaction, but they're not without their quirks. Regular cable replacements, indexing adjustments, and the occasional derailleur hanger mishap are part and parcel of the mechanical experience.
On the other hand, electronic systems, while precise, are not infallible. Battery maintenance, though not a daily chore, is crucial. And while modern systems are designed to withstand the elements, they're not immune to damage from prolonged exposure or a particularly nasty spill.
So, let's not pit one against the other. Both systems have their strengths and weaknesses. It's about finding the one that suits your riding style and maintenance preferences. After all, whether it's a mechanical purr or an electronic hum, it's all about the ride.
