Bitex makes a triplet hub. You can build your own wheels using that.
I'm rebuilding my triplet wheel and am having a carbon rim made with 16:8 angled spoke holes. I haven't had any issues with the 24 vertical holes I have now, but the wheel manufacturer recommended the angled holes, so I'll give it a shot. Only downside is that this rim must now forever be laced with a 16:8 pattern.
