It surely must look like a bike with a major manufacturing defect is being ridden... or a circus bike.
If anyone finds such a video online please do post a web page url.
The majority of chain wheels and cogs are not perfectly round and in setting up a fg or ss you do have to spend a little time making sure chain tension is consistent and there are no points where the chain binds.
In setting up a Biopace as a fg/ssyou set the chain from the point of highest tension, back it off so it does not bind at that point and you are good to go..
