Shimano’s three-pulley rear derailleur could revolutionise drivetrain design

I've never had a rear derailleur cable "snap"; they stretch, fray and may eventually break right at the pinch point but these are either slow delays with obvious warnings or easily fixed on the trail. Compared to a connectivity or battery issue? They don't have nearly as high of likelyhood.

I’ve seen cable breaks happen, though not frequently. I’ve also seen chains break a lot more frequently, I know of 5-6 instances where it happened last year alone locally. All of these were a result of complete lack of maintenance as you point out, though I suppose it would be possible for a newer component to not show signs of wear and still fail.
