2010 is the tenth anniversary of the SpinFaktor line of yo-yos so YoYoJam thought it would be fitting to create a new updated version and call it the X. The SpinFaKtor X takes a new approach on plastic-metal hybrid yo-yos putting the aluminum right on the body of the yo-yo for an all new look and feel. The YoYoJam SpinFaKtor X yoyo comes stock with the new Solid Spin™ axle system silicone response system and a half SPEC bearing for responsive play.
