Very nice setup Dave, and glad that the Dedome style trail mod works for you.
For Drone, drawing from Dedome website, explaining how the trail reduction on the BMW with telelever is achieved.
Sorry it is in French, but basically the drawing shows you how your can reduce the trail without changing the angle of the fork and the position of the wheel. The OEM trail is130mm, and with the Dedome mod it is reduced to 45mm
If you need some translation, I can do it tomorrow.
