That's pretty neat, but I can't see that holding up to some serious high-load chevrolegging. At least with a chain and sprocket, the chain uses a little over 50% of the sprocket to transfer power. That "CeramicSpeed" uses 2 little bearings to transfer power. They stated their goal was to reduce friction, they obviously accomplished that, but at what cost to long-term durability?
Color me skeptical. I bet the lycra crowd is drooling tho!
