All CS27s and RP30s have been on new rims for at least a month. RP24 and RP36 are still on the older rim for a few more weeks.
Keep in mind that the only guys having problems with RP ABS rims are at track with brutally solid boards. I have run ABS rim RPs for 2 years and I have not broken one yet. Oh...by the way...I have some pretty spectacular crashes so it not like I am not abusing them.
