Mind-boggling the myriad knowledge in this thread. Turner didn't start using a tapered head-tube in the Sultan until a later revision, around the 2011 model year. This is a 2010 model, and I had a 2009 model which I absolutely loved. I was adamantly looking for a later model for several months now, but none have come up in my size that I could justify. This frame came up with a BIN a bit below market value, in the size I needed, and came with the King headset. I pounced. Now I'm having a hell of a time finding the proper fork that isn't a tapered. I don't want to can't pay retail.
