i have just purchased a zwift ride and I am attempting to connect my kickr core to it. Question is do I need 2 thru axle adaptors ? and should they be in the box that came with the ride
You need the 142mm adapter (on the left side) and the spin cap on the right side. Those are parts 4 and 7 on this page: https://support.wahoofitness.com/hc/en-us/articles/360018850859-Updated-KICKR-CORE-thru-axle-adapter-installation
If you already own the trainer, the adapters would have come with it.
If the trainer is really old then it might have come with the older versions of the adapters, but they are readily available. There are third party sources for them on Amazon like this: https://www.amazon.com/AGILLE-Compatible-Stainless-WFKICKRTHRUAXLEKIT-Resistant/dp/B0CYLTG8DM
Thanks Paul great help
