TR 890 TENNIS RACKET

The stiffness rating of 69 greatly improves the racket's power, with little distortion on impact.
When choosing your racket, keep the following in mind:
Stiff frame: > 64 – 66 RA
Flexible frame: < 64 – 66 RA.
The stiffer the frame, the shorter the contact time: you lose control but gain power.

An inertia of 285 prevents the frame from distorting during fast acceleration, delivering power and precision. The higher the inertia, the harder the racket is to swing and manoeuvre, but the greater the power. The lower the inertia, the easier the racket is to swing and manoeuvre, providing more control but less power

The size of the TR890's head (640 cm²) provides power, forgiveness and powerful spin.
Its open 16 x 19 stringing pattern accentuates spin.
