This kit comes with everything you need to mount most 142×12 thru-axle bikes on your KICKR indoor trainer.
It includes the following:
Threaded Axle Spacer
Hub Width Adapter
Conical Axle Adapter
Flat Axle Adapter
XL Quick Release Skewer
Extended Quick Release Nut
Note: The KICKR is not compatible with the thru-axle itself; instead, we use this adapter kit to secure the bike in place. Please watch the installation video or read the adapter instructions before attempting to install yourself. This is for 142×12 bikes only. Not compatible with 135×12, 148×12, or any other thru-axle system.
