As near as I can tell, there's assymetric beveling in the profile of each link, so the chain can be lifted up more easily and with less travel off one sprocket to another. Without the side plates, the chain itself is also thinner, so less distance to go side to side during shifting. Also means more sprockets can fit in the same width cassette. Not sure any of this qualifies as a 'reinvention.'

More diagrams in the source patent. They won't let me direct link to the PDF.

It's a little sad that we need to actually say this, but:

Don't be an asshole or you will be permanently banned.

Respectful debate is totally OK, criticizing a product is fine, but being verbally abusive will not be tolerated.

Focus on discussing the idea, not attacking the person.
