The FD screw holes on the frame are positioned horizontally. The holes of the Shimano E2 (S2) fits on these screw holes. The holes of the SRAM low mount FD got the rght distance, but are not positioned horizontally, but with some offset. Despite of that, the bottom pull of the SRAM is going the same way as the Shimano FD. The cable is making a half circle starting on the bottom pull of the FD at the left, going up, to the right, down into the frame. Te get a correct angle, is had to start on the right, going up, to the left and then into the frame. I couldn't found a FD that pulls down this was and had the holes positioned horizontally.
