That's also how chain hoists work - I'm still amazed at how much you can lift using one!

I actually thought the article will be about Biopace bike chain rings: bikers are using them as an advantage in races (and it really makes sense!).

Supposedly, Biopace was shown to be counterproductive, while the newer Rotor Q-Rings are correctly designed.
