Sorry to hear that - this is the first case of clear nuts breaking reported on this thread. Has anyone else had issues?
JH's stance is there is no problem w/ the clear cables, that's why everyone was getting clear cables until they had aluminum nuts for the black cables.
So if you order a black cable today, you will get one w/ an aluminum nut. Clear cable, you will still get a plastic nut.
I have had the clear cable for 2 months now and the nuts are still perfectly intact.
