The rise of around 11 cm is correct for a Nitto Tech Deluxe, and you are stuck with that rise for that stem and that frame. I have similarly small frames (52 and 53 cm) and believe me, you're stuck.
Let me clarify. First of all, I am not using the Technomic Deluxe presently. I am using a conventional stem that is providing about 2-1/2 inches of rise. I wanted to change to the Technomic Deluxe for a little more rise and I was concerned about the max line showing when I inserted it as far as possible into the steerer tube. The Technomic Deluxe, when inserted to the insertion line, will provide 4-1/2 inches of rise. Actually that is a little more than I need, and since I can't reduce the rise by inserting the stem any further into the steerer tube, I am going to have the stem cut and sanded to provide about 4 inches of rise. I am satisfied that I'll get sufficient insertion (just under 3 inches) for the slightly shorter stem and have the height I want in relation to the saddle.
