I'm sorry if this is over debated here but I just wanted to make sure I don't make any mistakes with my wheel.
I'm planing on building a wheel with PlanetX 50mm carbon rims (16h front, 24h rear; I'm pretty light so I hope 16h front will be enough):

I've searched around the forum and found the ERD to be of 563mm (but not sure if it is different for internal or external nipples)
I would like external nipples, so need to make sure the ERD is still 563mm.
with these hubs from bikehubstore:
FrontHub: SLF71W - 16holes
http://www.bikehubstore.com/SL71W-p/slf71w.htm
Width: 100mm
PCD: 31mm
Center-to-Flange: 40mm (80mm flange-to-flange, 83mm counting the width of flanges)
Hole Diameter: 2.6mm round
RearHub: SL218 Rear Hub - 24holes
http://www.bikehubstore.com/SL218-p/sl218.htm
Lenth: 130mm
Driveside PCD: 49.6mm
Non-Driveside PCD: 38mm
Hole Diamter: 2.6mm
Left (NDS) Flange-to-Center: 37.3mm
Right (DS) Flange-to-Center: 17.1mm
Could you be so kind to tell me if my spoke length calculations are correct?
I used this calculator: http://www.wheelpro.co.uk/spokecalc/
I got these lengths:
Front:
Radial - 267.3mm ->267 or 268mm
Rear:
DS: 2x - 267.3mm -> 267 or 268mm
NDS: 2x - 273.4mm -> 273 or 274mm
I'm planning on using DT Swiss Revolution Spokes which comes with ALU nipples.
Are my calculations correct? I really need to make sure.
Thank you very much!
