That is a question for Elite’s Support. The Rizer can be paired to third party trainers (like Wahoo’s). Depending on your setup - Elite would be the best resource to tell if you how well steering and elevations controls would work.
- In a Wahoo-only environment (ex - if you have a KICKR Bike Smart + Play controllers) you can steer your avatar with either/or controller.
- Another complication is that the Rizer pairs over ANT+ to a supported third-party trainer. Since Virtual Shifting relies on Bluetooth - the folks at Elite are better equipped to answer your questions than I am.
Agree - the Click would be the simplest shift controller in your use specific case because you can place them anywhere. Zwift does not have plans to sell the Click as a standalone controller at this time.
