Overview

Since 2014, Hyper-G has endured as the top string choice for tennis players around the globe. Developed for an ATP top 50 player, this shaped co-poly with an impressive combination of spin and precision allows big hitters to take massive cuts at the ball without having to worry about overhitting. The square profile with sharp edges bites the ball at contact, generating massive spin. Topspin players who like hitting balls that dive sharply and explode off the court should love this string. With an unmatched selection of 7 gauges from 15L to 20, there's a Hyper-G for every playing style.

Best for

  • Heavy topspin players
  • Advanced juniors with fast, full swings
  • Players looking for spin + control at great value
  • Big hitters who need to keep balls in

Not ideal for

  • Beginners or intermediates
  • Players with arm issues
  • Those seeking comfort
  • Flat hitters who need more power

Pros

  • Exceptional spin generation from square shape
  • Excellent control on aggressive swings
  • Great value - half the price of Luxilon
  • Wide gauge selection (7 options)
  • Good tension maintenance
  • Proven at professional level

Cons

  • Not arm-friendly - medium-high stiffness
  • Low power output
  • Requires proper technique to access benefits
  • Square edges can notch quickly
  • Can feel dead when tension drops

Stringer notes

Pre-stretch recommended. Be careful with sharp edges around grommets. Square shape can cause faster notching. String 2-3 lbs lower than round polys.

Break-in period

1-2 hours. Settles in quickly and plays great once broken in.

When to replace

Every 10-15 hours or when spin generation noticeably decreases. Check for notching.

Hybrid setup ideas

  • Natural gut mains + Hyper-G crosses
  • Hyper-G mains + soft multifilament crosses
  • Great as crosses in any hybrid setup

Used by

Hubert Hurkacz, Sloane Stephens, Bob Bryan, Mike Bryan, Various ATP/WTA players
