does anyone know whats the erd on the new Mavic Open Pro UST rims?
It's on the cycle clinic web site. The rest of your question was answered on the previous page, but the TL;DR of it is "buy new spokes", round ones are not expensive.
Having built with the OP now ERD is 293mm not 589mm as it say on the rim. silly mavic ERD measured with 12mm sapim brass nipples. I am not sure CX-ray are a good idea. I am going to delete that option from the builds. The stiffer sapim race/force is a better idea.
