For firmware update process instructions, please see How to Update Firmware on KICKR, BIKE, CORE, SNAP, and ROLLR
KICKR CORE Firmware v1.5.36 - 28 October, 2024
- Updated: Zwift protocol version.
- Fixed: Virtual shifting would not disable when Zwift disconnects.
- Fixed: Auto-spindown errors when using virtual shifting in specific scenarios.
- In the previous firmware versions, there was an issue with the trainer calculating the correct spindown values during the auto calibration process in certain scenarios when also using Zwift Virtual Shifting. The conditions could result in the trainer reporting "ghost" watts (watts while coasting), and could result in a power offset throughout the ride. If you are currently experiencing "ghost" watts, this firmware update will not immediately fix the issue on its own, but having updated to the current firmware, the auto calibration process will fix the power offset over time without manual intervention. If you would like to resolve the power offset immediately, you can complete a manual spindown.
