Black rim, black hub, should I use black spokes?

Black all the way...
AFAIK Black DTs are anodised and will scratch and black Sapims aren't so won't... The Sapims are baked in some kinda hi-tech way that colours the metal itself so it won't compromise the spoke's strength... This may be marketing BS, but it's what I was told/read...
Black is of course also invisible to radar... ;)

I'm looking at using ACI stainless double butted spokes from cyclebasket, my wallet isn't quite DT sized this month.

ACI have a good rep. I've had no problems with mine :)

I've just had some black rims, black hubs and SILVER spokes built up - looks ream!

[FONT='Trebuchet MS']About the powder coating, I thought about it to, but my conclusion was that the powder coating will increase the thickness of the spoke, and maybe give problems with the holes in the hub; also the rubbing with powder coating will be much more difficult due to the nature of the coating: and I don’t know about bake a spoke…[/FONT]

What about rims? Do you think a rim will be OK to powder coated?

the thickness of powder coat is minimal at low voltage, not enough to cause problems IMHO. high voltage coating would be thick enough to, we did a bike frame of mine and got about .5mm thickness of powder, I also did some bolts at low voltage and the powder on the threads caused no issues.

the heat is about 200degC, steel and aluminium are fine.

Anyone found a place that anodises?

Could be fun.

There was someone on a MTB forum that did small batch annodizing for reasonable money, I can look up his details. Andizing only works on none ferrous stuff IIRC so aluminium and titanium are fair game but steel is not (so no stainless spokes) there are other plating methods for making stainless go black but the really good ones use lead so the ROHS rulings make them VERY expensive.

Find an electroplaters in Yell.com and call them, see what they can advise, where I get my fixings their local electroplaters charge £25/batch to do stuff in Nickle a passive black, but that is
a rate for a LOT of regular work.

I went for Black ACI double butted in the end.
