AIUI they claimed their headset design was far superior to the wedge system design which Cane Creek owned the patent for...until that patent ran out when they immediately switched and started producing conversion kits to retrofit to the older headsets.even 10yrs ago CK was ultra paranoid about folks ripping off his patents
I dunno, maybe that's an urban legend but I know for sure though that you can spot a steerer that's been in a King headset from a mile off and I've never seen another headset, no matter how poorly adjusted, damage a steerer in the way that a King will/can.
