This kit comes with everything you need to mount most 12x142 thru-axle bikes on your KICKR indoor trainer. It will work only with the 2014 and 2016 editions of the KICKR. 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 12x142 bikes only. Not compatible with 12x135, 12x148, or any other thru-axle system. If you have any questions, don't hesitate to contact us!
