YoYoFactory introduced the SPEC bearing to meet the needs of modern unresponsive yoyo play. Now considered the standard against which all other bearings are judged, the SPEC bearing along with its sibling the CenterTrac bearing come installed in most YoYoFactory yoyos. These bearings come dry ready for unresponsive play and fit any yoyo that takes a size C bearing. To lengthen the life of your bearing a tiny bit of thin lube will go a long way.
