Harvey is right that this stem can be assembled backwards, in which case it will point upward significantly. But, even assembled correctly, and depending on the angle of your head tube, it can angle upward slightly. I have an earlier one of these, the exact same stem but labeled "Ambrosio," assembled correctly and mounted on my '63 Frejus, which has a 73 degree head tube, and the stem is angled slightly upward. I think it would look better if it were at least level, if not downward sloping, but it's still a really nice stem and I'm glad I paid $75 for mine.
