No worries, let me know if you find out, mine is less than 1 year old with less than 2,000km outside. I'm in the same position that I want another colour but can't justify spending £170 to change the colour when mine works fine and is new.
Just took fork out and measured steerer - is 1 1/8 - 1 1/2 taper, and after looking on the saddleback B2B site, seems that would make mine an inset7 unfortunately! Your fork must be 1 1/4 taper.
