the steerer and headset on the A-D are BSC dimension ("English")

however the wall is a bit thicker than a regular BSC steerer yielding a stem diameter of 22.0mm rather than the 22.2mm one might expect, while the metric/french size is an actual 21.9mm

the manufacturer also has a steerer size unique to them of 26.0mm O.D.
afaik this is not employed with any of the models of the A-D range
