Note that they're rubber. You put them into the chain like a sprocket. If you're careful about it, you can arrange for them to be slightly compressed (which you couldn't do with a normal sprocket) when the suspension is at "neutral" position (where it would normally be while sitting there, and the longest distance/flattest chain). Then it would force the chain to "shorten" when it got the chance, like when the suspension moved.
