Someone opined in an earlier post that Shimano got the clocking completely wrong. It's true that BioPace is inappropriate for racers and others maintaining cadences of 90 rpm and above (which is what Rotor Rings, etc., are designed for) but not for casual riders and many sport riders, who tend to go for lower cadences of 60 to 80 rpm or thereabouts. Those are the riders who can benefit from BioPace rings, and there are a lot of those riders out there.
