This product is shipped with the following:

  • Threaded Axle Spacer
  • Hub Width Adapter
  • Conical Axle Adapter
  • Flat Axle Adapter
  • XL Quick Release Skewer
  • Extended Quick Release Nut



How to install the adapter

NOTE: Before installing the adapter, you will need to remove the existing quick release and R130/M135 hub adapter from your KICKR. Additionally, remove the two springs threaded on the quick release from the adapter kit, as they will not be required.

  1. Install the 12x142mm hub adapter on the non-drive side (label facing out) of your KICKR. Thread the axle washer on the drive side of your KICKR. Gently tighten with a 17mm wrench if required.
  2. Lower the bicycle rear dropouts onto the KICKR. Lift the front wheel slightly to ensure the bicycle is seated on the KICKR correctly.
  3. Select either the conical (a) or flat (b) frame adapter and thread on the quick release skewer before installing on the KICKR with the included skewer nut.
  4. Lock in place by lifting on the quick release lever.
