Ashaway MonoGut ZX series tennis strings

July 11, 2013

Ashaway, RI — Ashaway Racket Strings offers two versions of its popular Zyex-based MonoGut® tennis strings, 16 gauge (127 mm) MonoGut ZX, and 17 gauge (1.22 mm) MonoGut ZX Pro. MonoGut ZX Pro is a thinner lighter string, designed to provide even better elongation, snap-back and playability for players who do not require the added durability of a 16 gauge string. Both strings offer 100% Zyex monofilament construction, which provides exceptional dynamic stiffness and gut-like playability. The total lack of polyester increases elongation and decreases stiffness for comfortable soft power.

“Like natural gut, MonoGut ZX series strings provide exceptional energy return,” said Steve Crandall, Vice President of Ashaway Racket Strings, “better than any other synthetic material. This means more power. Also like gut, MonoGut ZX series strings remain soft at higher tensions, reducing impact shock. This results in more comfortable performance — what we call ‘soft power.’ MonoGut ZX offers more durability, while many professional players prefer the responsiveness of the thinner lighter MonoGut ZX Pro.”

Crandall added that reports from players of all stripes indicate that MonoGut ZX series strings also generate spin like the, “so-called high-tech polyesters. Because of the strings’ high elasticity and low coefficient of friction, players claim better snap-back for improved spin, better results from more compact strokes, and overall reduced impact shock and enhanced comfort.” Crandall noted few breakage problems have been reported, and quoted several players as saying: ‘Playing with this string is just easier;’ ‘Great power and spin;’ and ‘Totally different feel than when playing with other monos.’”

MonoGut ZX and MonoGut ZX Pro are designed for players seeking both gut-like playability and superior durability in a solid monofilament string, as well as for players using monofilament strings in hybrid stringing patterns. MonoGut ZX and MonoGut ZX Pro come in either a natural gut-like tan or fiery red. They are available in 40-ft (12 m) sets and in both 360-ft (110 m) and 720-ft (220 m) reels. Recommended stringing tension is up to 60 lbs. (27 kgs).
