DA 9001 chews RD cables too!

[kgreene10]

I've been using DA 9001 shifters for a handful of months now, but my rear shifter stopped working with about 10km (and one unfortunate climb) to go on yesterdays ride, leaving me in my 39x11.

It turns out that the cable had begun to fray and one broken strand of cable was sticking up enough that is blocked the shifter from moving.

Curiously, the fraying is not right at the cable head but starts about 1cm down and extends for about 1cm. There's clearly something rubbing the cable in the shifter assembly.

Has anyone else had this problem? I know that DA 9000 suffered from a problem with the cables, but I thought a) the problem was associated with chewing the heads off like my 7800 used to and b) this particular problem was fixed with 9001. Is my issue the same-old, same-old or something else?
