Abec doesn’t equal spin.
Abec is how close too the size inside outside diamiter and width, of the bearing. Is to the size it is marked as…
Basicly you know how some bearings fit super tight in a yoyo, but if you switch to another bearing in the same yoyo, it could fit more tight or less? Thats the effect of abec ratings.
LOL. The Admin in Icthus’s siggy is Icthus, the Mod is jhb, the user is Dynikus lol. And with yoyos, ABEC means absolutely nothing. It’s just a better way to sell bearings to yoyoers.
The only difference i could see with bearings for something so light would be Ceramic vs Steel. On a microscopic level, steel is impossible to to polish into a perfectly smooth surface, there will always be imperfections on the surface, ceramic is composed of smaller molecules which allows the manufacturer to create a smoother surface.
actually, if you live in a place with really high humidity, steel bearings apparently rust really fast. I was talking to this guy who lives by the beach, and he said that he constantly throws out steel bearings because they rust out, whereas his ceramics are fine.
Performance wise though, they’re the same.
