Not if your bike gets serious miles on it. The rate at which I got through gear cables and outers before DI2 was quite extreme. To keep good shifting I'd have to change the both at least every 2 months, and ideally do a strip down and deep clean on the derailleur.

Not to mention the constant adjustments of cable tension as the cables stretch.

With DI2 I've not adjusted or stripped down for a good 2 years and I still have perfect shifting.

That's an interesting observation. What conditions do you ride in?

I cycle a lot (more than anybody that I know personally except for my brother) and tend do do years with cables and shifters. Cable stretch requires the occasional twist of the tensioners but that's no big deal.

I can see how for you Di2 is not a luxury though. Really curious about your mileage and other contributing factors.
