The elastomeric polyurethane gives this grip the best balance between tackiness and absorption for a great feel.
Frame weight = 160 g
With its frame weight of just 160 g (unstrung), it's an exceptionally light, manoeuvrable racket. This accelerates your swing so that you can give the ball plenty of speed, making it perfect for advanced players.

Balance = 290 mm (unstrung)

Head size = 685 cm²
