Yonex Astrox 1 DG Badminton Racquet, G4 - Blue/Black

• 2-Knot (same Lbs for main tension and cross tension): Ideal for recreational and intermediate players seeking standard, consistent stringing.
• 4-Knot (different Lbs for main tension and cross tension — cross tension can be a maximum of 2 Lbs greater than the main tension): Recommended for advanced players, high-tension stringing, separate main/cross tensions, or hybrid string setups.
• Note: 4-Knot stringing is possible only for isometric racquets, not for all racquets. Not sure if your racquet is isometric? Ask our badminton expert.

Cross tension can be 1 or 2 Lbs more than the main tension (2 Lbs is the maximum). 4-Knot stringing is only for isometric racquets. Not sure? Ask our badminton expert.
