What sets Zero apart is its exceptional bite on the ball, creating unparalleled snapback that generates massive spin potential. This allows you to hit with confidence and create sharp angles that push your opponents around the court.

Availability

Zero comes in two gauges: 17G (1.23mm) and 16G (1.28mm). We explain how to pick the best gauge for you in this guide.

You can purchase Zero as a single 12.2m set, a bundle of five 12.2m sets, or a 200m reel for frequent stringers.

Vivo String: Control and Spin

Characteristics

Vivo is designed for players seeking exceptional control and spin with a firm response.

It is a hexagonal co-poly string that provides more direct feedback than both Zero and Sync, with a shaped profile that grips the ball to help you create dipping spin.
