I built them spinners up, bit surprised to see them on the net but hay ho that’s the way of the world wide web. As far as black and silver spokes go we keep a lot of size in stock of both colours but its a fact that DT do more chose in silver than black as you can only get equal number in black e.g. 258mm, 260mm. but that is never really an issue as you can get way with a 1mm either way. I would always recommend silver spokes as I feel they look better and age better and for some reason I just prefer to build with silver spokes. I have got the exact build on my bike but I have also tied and soldered them. If you want Chris drop them into the shop and I will tie and solder them for free as they have got a bit of exposure. Its something I have been doing a lot trying to bring it back a bit. Here is a link to mine http://www.pinkbike.com/photo/2709037/
