*** NOTE: KICKR v6 and updated thru axle adapter kits come with modified conical lock nuts.  If using a v6, MOVE, new CORE, or this updated adapter kit, please use the shorter conical XDR lock nut provided with the trainer or updated adapter kit, rather than the cylindrical lock nut pictured above.  If you have a question about if your bike requires an updated adapter kit, see our article on KICKR Bicycle Compatibility.

Required Tools:

Installation Steps:

  1. Start by using the chain whip (or chain vice as pictured) and lockring tool to loosen the lockring and remove the existing cassette
    (skip this step if a cassette is not present, like in KICKR CORE initial setup).

  2. Use the 17mm* cone wrench to remove the existing original lock nut and freehub body. Hold the pulley with your free hand for stability.

    *KICKR v6 and updated thru axle adapter kits come with lock nuts with 14mm wrench flats, rather than 17mm.
