If you have to run both a short stem and a zero offset seatpost to make the cockpit right for you then your top tube is too long for your reach. Simply put, your bike is too big.
Wrong. I have short torso as compared to my femur length. My TT and ST lengths are appropriate for my body dimensions. I run 9cm stem instead of the Kona specc'd 10.5cm stem to accomodate my shortened reach. I choose to run a zero offset post because I am not so much concerned with the mythical KOPS position on my CX bike and am more comfortable with my saddle closer to the BB centerline. If I were to size down as you mistakenly suggest, the HT on my Kona would shorten increasing the saddle to bar drop. If you reread my original post, what I was addressing is the suggestions to the OP to size down because of standover height, BB height, or tire size.
