The SPEC bearing is the successor to the beloved Dorothy bearing. The SPEC is a smooth bearing that isn’t stock for all YYF yoyos. ---

SPEC only comes on metal YYFs, correct me if I am wrong. ---

I’m pretty sure they come on every YoYoFactory yo-yo. As I’ve said before, “Bearings are bearings are bearings.” That goes for SPEC bearings as well. ---

> [@Yummy](#): > > I’m pretty sure they come on every YoYoFactory yo-yo. As I’ve said before, “Bearings are bearings are bearings.” That goes for SPEC bearings as well. alright, if I give you a normal stock bearing, and then a KK bearing or a 10Ball bearing will you feel a difference? SPEC bearings,similarly to SPEED bearings, are only stock on those really special yoyos, meaning that you won’t find a SPEC bearing stock on a Duncan Mosquito. Go here to the store area and look at the YoyoFactory Velocity. You’ll see that there isn’t a SPEC bearing stock. ---

You’ll see that there isn’t a SPEC bearing stock. SPEC bearings are nice, but really aren’t all that special. They come stock in YYF yoyos, and they are YYF’s bearing, so naturally they won’t be in a Duncan. Where do you see that the Velocity doesn’t come with a SPEC? I’m not positive but I’m pretty sure it does. ---

The Plastics do come with SPEC’s, but they are not engraved. Also, YoYoBlaze - the SPEED bearing is like the SPEC bearing, not the other way around. SPEC’s are stainless steel bearings made by Central Bearing Company. ---

I’ve gotten & minute or longer spintimes with all kinds of bearings. From stock duncan’s to ten ball. My only thing is the ten ball is more stable due to the extra two balls. It can remove bearing vibe just by putting one in a vibey yoyo. And I’m not talking about the 10ball from onedrop. I’m talking about any 10 ball made. AIRG or onedrop or any other bearing with 10 balls. So as to what mrcnja said. A BEARING IS A BEARING IS A BEARING!
