I have the decals, just not fitted them. On the MK II the frame is Powder coated, so the decals have to be fitted after the frame is finished. On the MK III the frame is painted with a 2K basecoat, then the decals are applied, and then the 2K clear coat is applied. So on mine I can choose if I want to apply them or not ... I probably will now the build is complete and I'm not likely to whack them with a tool if it slips. I've only fitted the Reynolds 531 fork decals, and the Thorn 969 and Rohloff "Steel is Real" decals at the moment.
The spec did include a front rack, and I have it ready to fit, but decided to hold off until I got and fitted the Edelux II front light. When I've decided what cable routing I'm going to use then I'll fit the rack.
The grey wouldn't have been my first choice ... although our other tandem (Dawes Super Galaxy circa 1989) is graphite grey, Blue or BRG metallic would have been my choice. However, although described as "Steel Grey" I was expecting something along the lines of plain of battleship grey, what turned up surprised me completely, it's a sparkling metallic grey, I'm not sure a photo can do it justice, but I do agree that grey is certainly subtle.
