Before you use your CycleOps Trainer in Zwift, you may want to calibrate it. While you currently can't do this in Zwift, you can through CycleOps' Virtual Training Program.
Calibrating your CycleOps Trainer (PC)
Download the Virtual Training Program from CycleOps's website, install it, and launch the program. If you don't have an account, you can create a free trial account. Log in, and plug in your trainer.
After logging in, click the "Settings" button from the menu on the left.
The Settings page will open to the General tab. Click the Bike tab.
Once you're on the Bike tab, you'll see an option to select your trainer. Click it.
Select your trainer's brand (CycleOps).
After you've selected your trainer, it should show up under "Your Sensors." Click your trainer's name.
Clicking on your trainer should open the Trainer Detail page. Click Calibrate Trainer.
This will bring up the calibration prompt. Simply follow the instructions for performing the spindown, then close CycleOps Virtual Training once you're done calibrating.
Connecting to Zwift
After you've calibrated your CycleOps smart trainer, you can follow the instructions for Starting a Ride in Zwift to pair it with the game.
Most other trainers are both ANT+ and BLE. All CycleOps smart trainers will pair under the Power and Controllable Trainer categories.
If you're having issues getting your trainer to work with Zwift, you can submit a ticket, and we'll be happy to help.
