I'm using a Wheelmaster 24 x 2.125 36 hole hoop that I purchased from Niagara Cycle and a 1971 Sturmey Archer 3 speed type AW 36 hole hub. I have looked online at spoke sizing calculators and am completely confused. There seems to be so many things to measure and I don't know if I am even measuring correctly. If anyone can tell me what size spokes I need I would greatly appreciate it. Thanks...Jim
