Why does people keep guessing what is not being said?
I have a wheel on my lap, I just finished lacing the spokes on the wheel. It is a rear wheel, that needs to be dished. Single walled rim construction. Once everything is tensioned I'll hit the sticking spokes with a file to stop them from poking the inner tube. The file is an American pattern, single cut. All I needed was the formula so I could figure out that I needed to dish it 6.4mm.
