What I've heard is that they tend to start misbehaving right before they snap. So there's no real warning until it's too late. My bike shifted perfectly even with very noticeable fraying. My suggestion would be to peel the shifter hood cover back and inspect the cable at the shifter cable guide every so often. It only takes a minute or two.

Sounds high. Is that for a complete set? You really only need one shift cable ($3 US, or $6 for Jagwire coated).
In my experience there isn't much warning, but if you notice that you have to adjust your rear D cable tension, and it won't seem to stay adjusted, that's the first symptom, time to replace the cable. Also, I haven't kept close track, but, to me, it does seem like the Jagwire cables last longer than the DA9000.
Exactly the same symptoms in my case. I lost the 3 biggest gears 20 miles out then snap the last 10 miles. My local LBS replaced the feral with a different type that came with the original build. It does not have a sharp edge that appears to be part of the problem where the cable is wearing. It makes sense, I hope to have a better result in 4000 miles.
Let's finish the ride with a 20% grade.

OK folks, help me out here: I thought the redesigned 9001 shifters were introduced specifically (if not publicly acknowledged by Shimano) to correct the cable-shear problem? That appears to be not necessarily the case. If so, then what is the difference between the 9000 and the 9001 shift levers? I would like to switch from SRAM Red 10 speed to the Shimano 9000 11 speed for reasons chronicled on this forum (SRAM Red front der simply does not play well with Rotor cranksets) as a bridge until Shimano introduces a real wireless shifting system. If the 9001 levers are still faulty and eating cables, I might reconsider that a bit - or at least not pop for the more expensive 9001 levers.
Thanks,
Chris

In my experience, the 9000 cables are good for a season or two. Thats way beyond the change out frequency for pro team cables. And for the diligent and well maintained bike. So really this is not a design defect. I think this is the tradeoff for the low friction shifting performance. And as butcher says....and I have said, if you don't like it, go electronic.

New here. Howdy folks!
I work in a shop and having learned about the amazing qualities of these polymer cables I set out to learn more. It seems there are two (2) levels of polymer cables put out by Shimano. If you look at the cable kits/sets there are DA and Ultegra level. I learned that the DA cable are more expensive to manufacture since they are smoother than the Ultegra cables... I'm thinking the strands in the DA cables are finer. Of course I ordered a DA brake and shift set... and just found this thread.
I've heard from a couple of pro mechanics that Shimano shifters are tougher on cables and require more frequent changes than others. They change their cables so often that it's not an issue for them.
I wonder if the cables on Ultegra shifters are breaking as frequently?
