hey, i was wondering what the diference is in bearing sizes, like the genesis how there is a small and large bearing, and also, what is better center trac or konkave or konkave ceramic?
a,b,c,d bearings are the standard in yoyo’s. B being the least used.
The a bearing or small bearing is the same bearing you’ll see in a FHZ.
The B bearing is the same you will see in the menehune or a few other wierd yoyo’s.
The C bearing is the normal large bearing which is found in most YYF, YYJ’s and most other yoyo’s.
The D bearing is in between the C and A bearings. It’s what SPYY and Hspin use.
KK’s and centertrack bearings are worthless imo. Flat bearings are worth more in my book. You won’t get any more performance out of those bearing’s as you will the flat.
