While both offer outstanding, modern performance in their own right, each one is tuned for a distinct style of play.
In this guide, we’ll break down the unique attributes of Sync and Vivo, and help you choose the right string based on your approach to the game and your performance preferences.

The round profile and advanced string coating promotes dynamic string movement, meaning you get excellent snapback in your shots.
We engineered Sync to offer outstanding tension maintenance, so you'll benefit from long-lasting playability and a reassuring level of control session after session.
