I don't think they are claiming any power is transferred by the other side, just that it forces a more uniform fit and distributed the power transfer over more

  They very much are making that claim. > The future apparently isn’t far away, as New Motion Labs has developed a new Dual Engagement chain that is supposedly able to transfer high power on both sides of the tooth, over nearly all the teeth available to the chain.

    > According to New Motion Labs, because the chain engages on both sides of the tooth, it is effectively locked in position, theoretically spreading the power distribution over many teeth, increasing efficiency, and reducing wear. 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.

    See my other post theorizing about how it might actually be advantageous despite looking crazy. Perhaps a case of marketing guy who doesn't really understand what he's selling effectively outranking the engineer?
