Actually, the hottest carbon spoke wheels IMO are the Corima 4-spokes >>> http://www.chainreactioncycles.com/M...?ModelID=36317

I had an IO but had to sell it because I couldn't control it in windy conditions; it's really intended to be used on indoor velodromes where there is no wind. Also, they are rather heavy, almost as heavy as a carbon disc. It was freakishly fast though, and I would have set my best times on it if I just could have controlled it.
