Duncan Size bearing?

Are they desame sizes?


They might be close, but they aren’t the same size. If they were, they would say that they could be used for all those yoyos, the Duncans and the Raiders.

So, the stock duncan bearing on a Speed Beetle doesn’t fit on a Yomega Raider right?


The raider bearing is about half the size of a duncan bearing.
