KSETT: Virtual Shifting
Any smart trainer, any app
Free · In‑App Purchases
Add virtual shifting to the training app you already use. Custom drivetrains, Bluetooth shift controller support, ERG Intensity, Apple Watch heart rate, and live metrics.
Real gear feel for your smart trainer, in the training app you already use.
KSETT adds virtual shifting to Bluetooth smart trainers. It sits between your trainer and your training app: your app sees KSETT as the trainer, and KSETT controls the real trainer, changing resistance as you shift through your chainrings and cassette, just like riding outside. You don't need a cassette on the trainer or virtual gearing support in your app.
HOW IT WORKS
1. Open KSETT on your iPhone and connect your smart trainer
2. In your training app on another device (iPad, Mac, Apple TV or a second phone), choose KSETT as your trainer
3. Ride and shift with the big on-screen buttons or a Bluetooth shifter
WORKS WITH
• Smart trainers that support Bluetooth FTMS, such as Wahoo KICKR models
• Training apps that connect to Bluetooth FTMS trainers, such as Wahoo SYSTM, MyWhoosh and Zwift
• Zwift Click and CYCPLUS BC2 shifters
• Bluetooth heart rate straps, cadence sensors and Apple Watch
RIDE FEEL
• Gears based on your real drivetrain's tooth counts, so every shift feels the way it would outside
• Works in Level/Sim mode and responds to your app's hills
• ERG aware: gear controls step aside while your app sets the power, and ERG Intensity raises or lowers the target 5% per tap
• Add a simulated hill on top of your training app's grade
• Haptic feedback on every shift
RELIABLE
• Keeps relaying with the screen locked or while you use another app
• Reconnects after a trainer dropout and re-sends your app's last target
• Built-in User Guide, troubleshooting tips and debug log
