I'm always interested in alternatives to a chain.
- It’s always an interesting chain of events to see whether or not these alternatives gain traction
  
  I'm hoping they go into a high gear soon
- If it ain't broke, don't' break it. While nothing is perfect it is really hard to do better than a chain.
Chains are good because they distribute the torque across multiple gear teeth. This doesn't, so I imagine the wear on the drive gear would be much greater, especially since the teeth are smaller. Overall not impressed.
- There are plenty of motorcycles have shaft drives. I think they will be able to make a shaft that handles the torque of a person peddling
Will there ever be a bevel gear drive shaft on a mass production bicycle? The shaft and supporting structure has to be really ridigd to keep the gears meshing properly. That means more weight and more expensive. Also, expensive replacement parts.
I mean if they backup the talk with a 10k mile warranty I can see it.
