Wahoo XD/XDR Freehub Body for KICKR and KICKR CORE (2018+)

Wahoo XD/XDR Freehub Body for KICKR and KICKR CORE (2018+) is a replacement or upgrade drivetrain component for indoor cycling trainers. It changes the trainer's cassette interface so it can accept SRAM XD- and XDR-compatible cassettes. This lets a bike or cassette using either standard be matched to an indoor training setup. The freehub performs a mechanical mounting role rather than recording or displaying training data. Its purpose is drivetrain compatibility at the trainer, not adding a separate training function.

The component also serves as a direct replacement when the trainer's original freehub body needs changing. SRAM XD/XDR cassette standards appear on modern road, gravel, and mountain-bike drivetrains, covering several common bike types. Installation is designed as a component swap, and the package groups the specified fitting hardware with the freehub. Buyers still need to check both trainer generation and cassette standard before choosing it. The accessory is therefore most relevant when retaining an XD/XDR-equipped drivetrain for indoor riding or restoring a compatible trainer.
