Sometimes less is more! The Zoom is specially designed for young ropers just getting started or serious competitors in long-reaching dummy roping events. It has a feel that is also preferred by adults that need a smaller, lighter rope. The Zoom is slightly smaller in diameter than other lite ropes in the Classic® line, yet it is made with the same four strand Coretec technology that has become the choice of four strand users. Size: 5/16 Full. Length: 30. Lay: XS.
