Yeah, I'm also wondering about how much energy it takes to "lock it in place", and then, of course, unlock it.

I've been a cyclist for 30 years now, and there's always been a steady stream of 'amazing! revolutionary!' things like this, but mostly it's incremental improvements. If it pans out, great, if not, c'est la vie.

Spreading over many teeth is very interesting, I'm pretty sure that it doesn't happen in real life. You'd need elasticity to exceed imprecision and there's definitely no place anywhere in chain or sprocket were you'd not try to avoid as much elasticity as you can.
