This is the unique ball-bearing counterweight from the mind of multiple time World champion Takeshi Matsuura! This counterweight was designed to get through a long freestyle with perfect string tension.
Each counterweight features a bearing inside the dice and a threaded string on a bead allowing for complete rotation of the string during any counterweight tricks. This gives your string the ability to rotate freely and leaves you with a nice neutral tension that won’t interfere with your tricks!
