Cool, thanks. I was going to use a spoke length calculator for radial front/2 cross rear. What lacing did you calculate for?

Also, the IRO published info is at the bottom of this PDF:

289mm is for 3-cross front and rear. I bought a couple boxes of 100 because I can use the same length spoke all around on my IRO builds. :D
