Magic yoyo

Are there any magic yo-yos that will take half bearings?

You can most likely put a half bearing in any of them with a shorter axel.

Yes but which one has a shorter axle?

Besides shorter axle, the bearing post should also be short.
I immediately think of sandpapers.

So I should sand down the bearing post if it is to big? and find one with a short axle.

Unless you know the risk of sanding the yoyo, I recommend you don’t. But if you know what you are doing, simply sand the bearing post and axle to make them shorter… if you have grinder that will be a lot quicker though.
I assume “half bearing” you are talking about is the same size with C bearing except it’s half the width?

Yes i do know what i’m doing an yes it is half the width of a size c bearing.
