Removing BIOPACE Crank - Help Needed

TheBrick(Tommy) I am not saying the difference in chain tension is massive, it clearly depends on how much of an ellipse the chainring is but there will be a difference in chain tension. Sheldon agrees with this point. Whether it is acceptable to you in personal. Most people get pissed of with cheap normal chainrings because they are not very round let alown a chainring designed and built not to be round.

Here here! My Shimano chainring is in no way perfectly round. But once I realised this I just adjusted to suit. Guess it's the same with Biopace.
