My Thru Axle Is Loose on the Non Drive Side of My Tacx Trainer

When installing your thru axle bike on a Type 1 Tacx smart trainer, you must use the Tacx thru axle adapters that are included with your trainer to convert your thru axle bike to quick release. For the non drive side, Tacx provides two inserts with the adapter: a flat insert and a conical insert to match your bike frame. If the insert is too long for your bike frame, it will “bottom out” on the non drive side when tightening the quick release skewer before your frame is pulled tight against the insert face. The result is side to side play. For these bikes, a custom adapter is needed.
