Tornado 17G/1.23 String Anthracite

Signum Pro’s latest string offering, Tornado is a heptagonal-shaped co-polyester string offering a high level of dynamic power while offering exceptional access to spin. This string is axially twisted and greatly increases the spin potential when compared to traditional round strings. Signum Pro Tornado also offers excellent playability and comfort for a co-polyester string. This next generation string offers a new optimized molecular structure which in result makes the Tornado hold tension remarkably well. The Tornado offers excellent ball control and is among the most durable poly-based strings we have play tested to date. The unique anthracite (black) color looks great on nearly every racquet. Tornado is part of the new Blackline® power series from Signum Pro.
