The Osymetric ones made me feel seasick......
Exactly. Modern evangelists say that the Biopace oval was on the wrong timing of the power stroke. These days the oval is clocked 90deg to what it used to be. Very different degrees of ovality as well.
TBH I tried one and swapped it out again after a few weeks. I have a few different bikes and the first half hour of every ride felt weird if I’d ridden one of the others in between. Couldn’t feel any magical benefit either.
Try it out but give it a few rides just to get used to the difference.
