I have recently received the DM, Speeder, Legacy, and Sunset Trajectory. I have also received the KonKave Bearing. I was hearing that if you put the KonKave Bearing in the DM, Speeder, Legacy the yoyo will crack. Is this true? Is there any way to prevent it but still have it in the yoyo.

First of all, I think this should be in the General Yoyo Forum.  
Back on topic, no the KK bearing won’t make the yoyos crack unless you have the wrong size. Andre actually uses a KK bearing in his Dark Magics as the one and only mod.
