YoYoFactory CBC Center Trac Large Bearing (Size C)
Center Trac bearings have a small lip on each edge which creates a track for your string to sit in the middle - this keeps it away from the response system a little more, causing your YoYo to be more unresponsive. This also makes string play smoother, as it keeps it in the center, away from the sides of the YoYo.
Please see the specification tab on each YoYo product page to determine what size of bearing that particular YoYo uses.
