My knees prefer the apparent even effort around the clock from the Biopace. I can't quite tell from the pictures..
I know a lot of people say Biopace feels like a pedal spindle is loose or bent or something..
That's pretty interesting, I went directly from a Biopace to the Oval-tech and never noticed that they were clocked differently. I guess everybody wants what they don't have, because on my long term to-do list I intend to replace the ovaltech with a smaller triple, like a Sugino XD600, to make my upper ring a little more useable.
