OCHO TNT Rx

Clear

The first solid core, synthetic gut string construction that features an octagonal shape with 8 sharp edges for maximum ball bite.

The benefits for the all court player are greater spin and a livelier response for more feedback.

Ocho TNT is for the synthetic gut player that has made a change to polyester strings, or the synthetic gut player that is considering making a change to polyester strings and shouldn’t.

Ocho TNT is the perfect string for the solid core, synthetic gut player that wants to experience the spin and control benefits that a polyester string can provide while retaining the power and feel of a solid core synthetic.

TNT2 Technology
TNT2 Technology enhances GAMMA synthetic strings offering the greatest combination of power, control and shock reduction of any premium tennis string including natural gut. This second generation Thermo Nuclear Process greatly improves two key factors that relate to a string’s performance: dynamic elasticity (storing energy) and dynamic resiliency (returning energy to the ball). When these two important factors are enhanced the ball will not only stay on the strings longer for maximum control and accuracy, but also return more energy to the ball for increased speed and power.
