By "horizontal piece" do you mean the carbon fiber beam? No, that is not round. The top is rounded but the bottom is flat and it is about 1 1/4" tall and wide. A 1 1/8" stem would not fit. But maybe I could get a replacement seat bracket and slide that on behind the saddle and use that to mount a pack somehow (maybe with some sort of "seat rail" like frame).
