Anodizing wears out pretty quick.
Ano coat wore off the rear rim I'd built up over the course of the first 150km ride. If your buying these rims you need to embrace the silver brake track
For some other comments & want of a better place to put them;
In terms of build & rim regularity they seem pretty even & balanced. On the 20h / 24h rims I built up the 24h was perhaps .5mm out of vertical across the joint (measuring using dial gauge on park ts-2).
Running 24h rear on a dt 240 with DBs makes for a slightly flexy build imo (@ 73kg rider weight, 6ft). Given this point & the spoking, I may well rebuild the rear to comp spokes to add some more structure to the strength on the DS - so perhaps some food for thought if your considering a build with this rim & eyeing the lower spoke counts.
Other notes are that the tire profile is wider than compared to firecrest404 rim - with a vernier caliper & pro3 michelins 23mm on both, the archetype has another 1.5mm width. I had been pretty convince from eyeballing the profile that the width was wider than the alpha340 with pro3 mounted, but the vernier says its the same fwiw...
