Ok , I'm working on building a rear wheel, Its a H Plus Son Archtype, with a Dt Swiss 350 road hub. The erd as I measured it using Roger Musson method in his e-book is 592. I have used 4 different spoke calculator's.
1. Prowheelbuilder.com, nds=288.6, ds=287.2
2. Dt Swiss, nds=288.6, ds=287.2
3. WheelPro(Musson site), nds= 288.4, ds=287
4. Bikeschool.com, nds=288.6, ds=287.2
My main question is about rounding the ds number, according to Musson you round up or down up to 1mm to the nearest number, there seems to be a consensus among the calculators, so the ds number is 287, do I need to round down to 286 or round up to 288?
