Hi! Thanks for reaching out with your question. You want to know if FulGaz works with the Wahoo Kickr 2 when using the Zwift Cog setup, right? That's a great question to clarify.

From what I understand, FulGaz is compatible with all models of Wahoo smart trainers, including Kickr 2, providing full automatic resistance control and power readings. So, the trainer itself should work well with FulGaz.

Now, regarding the Zwift Cog—which is a special cassette and shifting system designed primarily for Zwift compatibility—there’s a bit of nuance. The Zwift Cog changes how your trainer's drivetrain interacts with the cassette but currently, Zwift does not support virtual shifting functionality on Wahoo Kickr trainers—the physical shifting happens on your bike, but Zwift itself doesn't virtually control the shifting on Kickr.

FulGaz, meanwhile, connects to your Wahoo trainer over Bluetooth and controls resistance based on its own ride simulation, but it doesn't specifically integrate with the Zwift Cog hardware or software features. This means you can use the Zwift Cog cassette physically on your bike setup, and your Kickr 2 will respond to FulGaz normally, but the virtual shifting features from Zwift linked to the Cog won't impact FulGaz rides.

In summary:

1. FulGaz works fully with Wahoo Kickr 2 with automatic resistance control.

2. The Zwift Cog is a hardware component mainly for Zwift's virtual shifting experience; FulGaz does not utilize virtual shifting, so it does not specifically require or support the Cog features.

3. You can physically use the Zwift Cog cassette on your Kickr 2 with FulGaz, but the virtual shifting from Zwift won't affect the FulGaz app experience.

If you're looking to pair FulGaz with your Kickr 2 and Zwift Cog setup, the trainer will work fine with FulGaz, but the Zwift Cog’s unique features are not utilized by FulGaz.

Would you like guidance on how to connect your Wahoo Kickr 2 to FulGaz on your Windows 10 device? Or any other assistance with setup?
