Smart Training
When connected to a compatible app, the KICKR CORE can automatically control resistance according to the workout, virtual terrain or selected training mode. This allows realistic simulation of climbs and structured power-based workouts.
It works with platforms including Zwift, TrainerRoad and Wahoo's own training ecosystem, with ANT+ FE-C and Bluetooth allowing compatible software to control the trainer.

The standard KICKR CORE is supplied without a cassette, allowing you to install a cassette appropriate for your bike. Wahoo supports various drivetrain configurations, and the trainer includes adapters for 130/135mm QR and 12x142/12x148 thru-axle setups.
A 1.8mm cassette spacer is included for applicable 8–10-speed cassette installations.
