I wasn't really surprised when about three spokes pulled through the RR415 rim - that was an experiment I was trying to see if I could get the PT wheel weight down somewhat. The RR415 rim lasted about three months. But I was kind of annoyed when I noted cracks around the nipples on the replacement RR465 rim a few weeks ago. I got about 6 months on the RR465.

This time I rebuilt it with an RR585. And cut the DS spoke tension down to 100 kgf or so - per Psimet reco on another thread.
Reasonable quality seems to define the problem with the rim. It does not matter that DT markets it.
I have tensioned a friends Sun CR18 to 130kg because the Powertap hub has more dish and the non-drive side was breaking nipples.
