Toroline O-TORO 1.23 Tennis String Reel – Neon Green (660ft)

Experience the string that has become Toroline's best-selling and highest-spinning polyester. Co-developed with former ATP World No. 21 Steve Johnson, O-TORO is engineered for players who demand explosive spin, exceptional control and surprising comfort in one premium co-polyester string.

Independent testing by Racketpedia awarded O-TORO a perfect 100/100 spin rating, confirming its elite spin potential. In additional head-to-head laboratory testing by Tennis Warehouse, O-TORO outperformed Babolat RPM Blast, delivering 104% more spin potential while being 29% less stiff, providing a noticeably more comfortable and forgiving response without sacrificing control.

Its hexagonal profile aggressively grips the ball, while the advanced co-polyester construction promotes exceptional snapback for heavy topspin and penetrating shot-making. Despite its spin-focused design, O-TORO maintains a controlled, predictable response that gives aggressive players the confidence to swing freely from every area of the court.

With outstanding tension maintenance and long-lasting consistency, O-TORO performs equally well as a full string bed or as part of a high-performance hybrid setup.

Supplied in a 660ft (200m) reel, it provides enough string for approximately 16 racquets, making it an outstanding option for tournament players, coaches and professional stringers.
