Interesting, thanks. Did you cut down ordinary spokes to fit, they seem to be at quite an angle to the nipples?
The chap who is going to build my wheel for me advised against it... he suggested it would put the wrong stresses on the hub. But then he seems quite a cautious type; he also said my seatpin is too long - its 750mm and made from a piece of stainless steel pipe. I said I'd rather take the risk of it snapping the frame than wreck my knees!
