Sorry to say I have not been able to find any info on them as well. I have a set that came on my Jekyll and have had no problems yet. We should assume they are production line OE rims. I compared them with the Mavic XC 717Disc/XT hub wheelset I have and they are heavier. I use XM 117s to rip the rock and stump trails(all mountain) here and the 717s on weekly epics(cross country) and general use. Happy with both.
