Wahoo KICKR Freehub Body (Shimano/SRAM HG)
The freehub body contains the internal bearings and external splines that support the cassette; over time, the interface between the pawls or the bearing seat can develop tolerances that manifest as lateral oscillation (wobble). Replacing the entire freehub assembly ensures the rotational axis is concentric and eliminates play caused by notched splines or worn internal races. This is the standard mechanical resolution for a cassette that wobbles even when the locknut is fully torqued.

1.85mm Cassette Spacer
The KICKR CORE uses an 11-speed road freehub body; when using 8, 9, or 10-speed cassettes, the stack height is insufficient for the locknut to exert clamping force on the cogs. Without this specific 1.85mm spacer behind the largest cog, the cassette will remain loose on the splines regardless of torque, resulting in significant wobble and poor shifting. This part restores the necessary axial compression to the drive assembly.

Cassette Locknut
Cross-threading or stripping of the locknut threads prevents the cassette from being properly seated against the freehub face. A damaged locknut may feel tight during installation but fail to provide the clamping force needed to stabilize the cog set, leading to perceived wobble during high-torque pedaling.
