Externally routed cable - no problem, a few quid, 20 minutes, job done. Internally routed cables? PITA, but a bigger PITA if they snap.  My good bike rarely gets wet, and has just crossed the 5,000 mile mark. When should the inners be replaced, and I guess equally important, what about the outer sheath?

The new STI's seem pretty bad for wrecking cables (5800 6800 r7000 and r8000) I'd recommend changing inner gear cables every 3k miles.

I had two snap both around 3k miles.

I think shimano fixed the shifter snapping issue. It was a major problem with 5700 / 6700 but they changed things up for 5800 / 6800 and I think that sorted it.

 

Nope.... still get the 58/6800 in for snapped off at the nipple....  many are found early (as I take a look now) and some are found with just a few strands left connecting the cable to the nipple..... 

Mine is a 2016 bike with 6800. Broke at the shifter.
