Tension for Juniors

46-50 lbs for juniors. Square shape grips well so can string lower for more comfort.

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.

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.
