marin man is right they are spinergy spox, magnesium hub, pbo fibre spokes and my ones are ceramic rimmed and NOS, the pair in the picture are off my killer V so they aren't for sale but I have a spare NOS front same spec but with white spokes.
As far as the spinergy xyclone goes it has the same spokes but that's where the similarity ends, my mate wanted a pair of wheels like mine and as I couldn't find any I bought the xyclones his was very disappointed.
