Grundsätzlich ist es möglich, Biopace- und runde Kettenblätter an der gleichen Kurbeln zu mischen, jedoch riet [[Sheldon Brown]] davon ab. Wenn mann Kettenblätter mischt, setzte man üblicherweise ein kleineres Biopace mit einem größeren runden kettenblatt zusemmen. Die Idee dahinter ist, die überlegenen Klettereingenschaften des Biopace-Kettenblatts bei geringen Kadenzen mit den Vorteilen runder kettenblätter bei schnellen Abfahrten und hohen Kadenzen zu kombinieren. | |||
The problem is that Biopace rings are more comfortable at low RPM's, and round rings at high RPM's. When you shift from a small Biopace ring to larger round ring, you go from a fast cadence on the Biopace to a slower cadence on the round ring--just the opposite of what is wanted. I have tried this arrangement on both a road bike and a mountain bike, and found it extremely irritating. Due to the need to work well with a front derailer, the large Biopace rings have less "Biopace effect" in any case: the variation in diameter the same, but this is a smaller percentage of the total diameter. | The problem is that Biopace rings are more comfortable at low RPM's, and round rings at high RPM's.

You can usually lower the bottom gear by installing a larger rear sprocket instead. | You can usually lower the bottom gear by installing a larger rear sprocket instead. | ||
