I assume it's the two spoke wheel
It's been out for a couple of years now... it's possibly* a pretty fast wheel actually, despite the fact that the "data" on their site would lead you to think it's all bulls#*7. Some whispers from people (that aren't sponsored) that it might be pretty fast, but never seen any "real" data.
It looks cool, but I'd want to see some hard data that it was really faster than a "known quantity" wheel before I paid ~$1700 for one.
*Dutch Tandem team used them at Rio for what that's worth.
