I am looking for a nice box or very slight aero profile, preferably eyeleted rim with unmachined sidewalls, 32 or 36 hole, in black, clincher only. Does such a rim exist? Are unmachined openpros available? Any suggestions will be much appreciated.

open pro cd's have an anodized sidewall that gives the appearance of being unmachined, but they are dark grey, not black.

Whoa thems expensive. I will keep them in mind.

a few Alex rims come in unmachined black. But they're not terribly "nice" rims.
How about disc-specific rims?

sun cr18 and m13II both come in all black. not the best rim, but if black is what you want...
