I have a VeloOrange touring hub, 135mm, 36 hole , 60mm spoke flange diameter, and considering building up a wheel w 26" Mavic EX721 rim 3 cross. I've gone through three different on line spoke length calculators and am coming up with three different length results varying by 3mm. If on the far off chance someone has built this combo or found a particular calculator accurate I would appreciate the feedback.
