New one on me, but I just work on my own bikes. Any idea how this happened? It is the original Jagwire Lex cable housing for the rear derailleur on my Jamis Renegade. Both ends look like this with half the wires of the housing shifted various distances out of the outer housing, and the outer housing torn up under the ferrules. I have seen frayed, but not that shifting of the wires. The bike is only 2 years old and has less than 2000 miles, mostly this summer. Cables are a bit to long after lowering the bars; so I just recut the housing for now and used a new cable. I wonder if I should replace all of this housing on the bike?
