I know wheels are supposed to be built the "right way" (just as everything else on bikes) but I wanted to know if anyone knew any defined tolerances beyond what is normal. I know the spoke must come up to the flat on the nipple, I was just curious if there was a "its not the MOST professional way to do things, but it will work for sure" kinda way. I supposed there isnt really one for wheels. I now learned 2 new things today (other was how to rebuild a rock shox lyric fork)

I detensioned my wheel over breakfast and got some 293mm spokes ready at work. i am literally about to rebuild my wheel.
