Actually there was an error in a run of YoYoFactory 888x yo-yos - this one run all shipped with center trac bearings. Technically a good thing for you as it is an upgrade bearing - but the standard 888x normaly ships with a Spec bearing. ---

Technically a good thing for you as it is an upgrade bearing - but the standard 888x normaly ships with a Spec bearing. Not to be offensive, but I would strongly argue against the statement that it’s an upgrade. In my opinion, and the opinion of many others, It’s a downgrade. Of course It’s subjective, but I feel if you can throw straight this type of bearing is unnecessary and does nothing but hold you back and make your binds slippy. I’d take a flat spec or a stock YYJ any day. ---

I personally don’t really care about the bearing and typically play stock
