Is there an adaptor for a quick release wheel on thru axel hub
Usually, switching axle standards is accomplished by switching end caps on the hub. Whether this is possible or not entirely depends on what hub you have. You will need to do some research on whether your new hubs have convertible end caps.
I believe there’s generic adaptors available to shim down a 12mm thru-axle down to a 5mm QR skewer, but that’s the opposite use case from your intention.
