l is the spoke length
rr is the radius of the rim
rf is the radius of the hub flange (measured to the centre of the spoke hole)
f is the offset of the flange from the centre of the wheel
x is the number of times a spoke crosses over another spoke
h is the total number of spokes in the wheel
dh is the diameter of the spoke hole in the hub

This will give spoke lengths which are a fraction of a millimetre too short.

Rather than go through all this, try calling Dans or Albes. They will help you out so much quicker.

Usually buying a mm extra is good, but not over that much cause then the spokes will be too long. A mm shorter is okay but the spokes are gonna be pretty damn tight and stuff.

Yea, but you need a micrometer to be accurate with your measurements.

I would call Dans or Albes or Empire.
