Hey all,
Need help with correct spoke length.
The wheels are -
DT 240s 6 bolt disc hubs front and rear (both 28hole), Sapim CX Ray spokes with 14mm nipples, stans Olympic rims (536mm ERD)

Here are my readings from the dt spoke calc -

Front Wheel -

Spoke length
precise le. 262.70 mm ri. 265.20 mm

rounded (incl. Corrections) le. 261 mm ri. 264 mm


Rear Wheel -

Spoke length
precise le. 264.00 mm ri. 263.20 mm

rounded (incl. Corrections) le. 263 mm ri. 262 mm

Can you guys tell me which length spokes i should go with ? I was thinking 28 x 262mm and 28 x 264mm
Cheers

Are you planning 3X? if so, your numbers look as close as you can get with CX-Rays.
Why 3X and why 14 mm nipples? Remember, I don't know your rims.
