Abstract: The invention relates to yo-yos and in particular high-performance ball- or roller-bearing yo-yos capable of extremely wide string-gap settings suitable for “new school” yo-yo tricks. The present invention addresses the need to center the yo-yo string on the bearing or bearing sleeve along the axial extension of the outer surface of the yo-yo bearing or bearing sleeve or in relation to the effective “string gap” between the opposed inner faces of the two yo-yo halves. The present invention also provides an effective and economical string-bearing surface able to span the wider string gap required by “new school” styles and modes of play. The present invention enables the variable stacking of successive lays of string either side of the securing loop during complicated yo-yo string trick routines.
