There is some interesting stuff here:
http://www.geocities.com/spokeanwheel/lacingsr.htm
My main concern is lateral stiffness in the front, and lateral
stiffnes and torque resistance in the rear. I don't want the brakes to
rub when I am out of the saddle, and I certainly don't want the
occasional "boing" feeling I get with the rear wheel on my lightweight
wheels when I stand in high torque conditions.
So radial in the front sounds like the way to go for stiffness. Heads
in. Pretty straight forward.
What do you guys think about the 2x NDS, 3x DS recommended in the link
above? And the reasoning?
