I was at my lbs yesterday. They had a pair of Spinergy Xyclone Disc wheels. What interested me, were the spokes. They are made from what Spinergy call PBO technology. They look like the stuff you'd make a washing line from, and they are a fibre spoke that you can bend, almost like a thick cord. Spinergy claim it's 25% more shock absorbent and 10 times stronger than aluminum spokes.
The spokes don't look like (from the picture at least) that they are usable on all rims, so they might be proprietary to Spinergy alone?
Down the line, I'd like to build a pair of wheels for my bike, and these spokes look kinda cool. Anyone got comments on them and the rims needed?
