I built my PT on the Nio30 rim with CX-Ray spokes to make it better wheel than an OP with straight gauge spokes. I destroyed my OP rim, prebuilt by Saris/PT, in less than 3000 miles.
The Nio30 wheel ended up being 50 grams lighter than the original OP. The rim itself was 25grams heavier than the OP, but the CX-Ray spokes were much lighter. The Nio30 wheel ended up being MUCH stiffer than the OP as well.
