Thanks for the link. It's funny how people are so resistant to innovation. "Biopace chainrings are often cited as the epitome of a solution looking for a problem among the biking press." While typing on a computer that likely contains a mechanical hard drive spinning at close to 10krpm, the author complains of a slight increase in mechanical complexity that will allow him/her to generate more power. The real question is whether or not the complexity is manageable, will it break down frequently? etc.

"People are so resistant to innovation" is one way to look at it. Another way to look at it is that sometimes innovation gets far enough ahead of expectations that it can't overcome challenges with user education and linkages to present technology. I remember using Biopace and the part I remember the most was going up a steep hill and losing traction because of the change in torque. I was riding a bike the way I was accustomed to pedaling but the power output would surge because of the change in mechanical advantage. Maybe I could relearn how to pedal so I could take advantage of Biopace but I really just wanted to ride, not maximize every degree of the pedal arc.

If you want to really muse about missed innovations, look at recumbent bike designs. Every one uses upright bikes today.

Biopace-like designs returned to the PRO peleton a few years ago, though the shapes are a bit more radical.
