Kirschbaum Helix (200 m)
Kirschbaum Helix is a monofilament tennis string manufactured by Kirschbaum. Its construction is similar to natural gut strings. By employing a special multi-stage production technology based on the hexagonal twisting of fibres combined with heating, a string with unique properties has been achieved. The multi-stage twisting process delivers increased string flexibility, which in turn ensures excellent playability and outstanding feel at the moment of impact. An additional heating process stabilises the polymer properties of the string, providing better control and longer tension retention. Excellent playability, an optimal combination of power and control, durable tension and stability.
