That isn't adjustable is it? Well, besides flipping it over.
The adjustable stems are heavy (if that matters to you), and are probably not necessary for most folks. If you leave a spacer or two above the stem, you can raise the bars by either flipping the stem or swapping the spacers. That is generally plenty of adjustment- again assuming the steerer tube hasn't been cut too short to begin with. Personally, once I get my seat and handlebars where I like them, the last thing I want to do is "adjust" them.
