I have a set of forks (Rock Shox XC/30/TK on a Focus Black Raider 2.0 2012) that measure 30mm at the bottom and 28.6mm at the top, (or 1 3⁄16" to 1⅛" in pre-enlightenment measurements). So they're tapered, but they're not 1½" to 1⅛" like a standard tapered steerer.
So are they tapered or straight? I am looking for a replacement because the dampener popped out of them and I need to know what to be looking for.
