uhm maybe this is such a newb question but i just wanna kow what’s the difference between this bearings,spec,dorothy and speed bearing.thamks.
They were made by different companies…
i mean differences like what’s there advantages and this advantages something like that.
If you mean the dif e yo bearing, the main difference is the shape of the bearing. The dif bearing is concaved (kind of groove on the surface of the bearing that helps the string centerd)
As for dorothy, spec and speed bearing, they basicaly the same, high grade stainless steel bearing that improved spin time
But i dont think that dorothy is on any now days yoyo, its used on any older yyf yoyo, such as the 07 888, now they use spec (the main difference i found is the cage design)
While the speed bearing is use by yyj on their metal yoyo
Thats all i know
well still that helped me understand a lil bit.thaks.
