You can find the list of compatible trainers here: Connect your Trainer (Compatibility Tool)
Your trainer may still be compatible even if it doesn't appear on the list. If you're using a classic (non-smart) trainer. (Some might refer to these as "dumb" trainers).
Select "My trainer isn't listed" to get the proper connection instructions.
Be sure to choose the Generic Power Curve. There's a fluid curve and a magnetic curve. Choose the one that best matches your trainer. For more information about Virtual Watts and what to expect, see Virtual Watts.
If you're connecting a set of rollers that does not have a matching power curve, please select a power curve for a set of compatible rollers that best matches the rollers that you have. (ie- how/if it applies resistance).
