Can you please elaborate on the wheel lacing?
I am very proficient at building and truing wheels, I used to race bicycles, and used to rebuild motocross wheels in the 80's.
When i had to build my beemer wheels I encountered difficulties, no matter what i did I couldnt decifer the behaviour of the these wheels.
After I think 2 days of frustration I decided to aproach it a a machine - I measured all the spokes to be the same length, and counted turns on the nuts, without any attempt at trueing - and got to within BMW spec for these wheels.
I wonder If you did it differently, and if so, if you please let us hear a little about it (even though it's much less interesting than all the other amazing stuff you do!).
