The changes to the Tune hubs are a running change and are not done as a model year change. When Tune runs out of existing hubs they’ll begin to switch to new hubs. Externally you won’t really be able to tell the difference. The only thing I can suggest is to buy it from a dealer you trust and rely on them to give you the correct information as to what’s inside the hub. Though the only way the dealer will know is if they take the time to open it up and look as Tune is not marking the hubs any differently.
