Whats the most infuriatingly unfixable electronic groupset issue youve ever encountered, and did you end up having to replace the entire system or resort to some MacGyver-esque hack to get it back up and running?
Im talking about those mind-boggling, hair-pulling, controller-smashing problems that make you question the very fabric of modern technology and wonder why we ever abandoned the simplicity of mechanical shifting.
Was it a faulty actuator, a malfunctioning battery, or perhaps a mysterious issue with the wiring that had you scratching your head for hours on end?
Did you stumble upon some obscure solution online, or did you have to break out the multimeter and get down to some serious DIY troubleshooting?
Im not looking for any straightforward or run-of-the-mill problems here, but rather the kind of head-scratching, soul-crushing electronic groupset issues that make you wonder if its all worth it.
So, lets hear it - whats the most baffling electronic groupset problem youve ever encountered, and how did you manage to resolve it (or not, as the case may be)?
