CO (cadence optimizer) is a combination torque analyzer and preference indicator.
The more you ride at your natural cadence at various power levels the more you’ll be in the green zone.
CO has no effect on power control over the trainer, but you will notice a difference in how well you can maintain target power at various rpm. Everyone has a sweet spot especially during high watt intervals.
What most find useful with CO is the fact the band moves to your preferred cadence range before the interval starts. You can spin up before a hard interval and avoid hitting a wall when that interval starts.
