I have an ACS double stem, the V shaped kind with two clamps. Problem is, no bar to match? I'd prefer something with about a 2 inch rise, which a lot of them seem to be, or the ones I have seen anyway. Here is the stem I have. Well, aside from someone painted the lower part black. Borrowed someone's pic.
