FEATURE
TK-9900 is engineered with Energy Bow technique to reinforce the elasticity and rebound speed, creating incredible repulsion after each shot. The grommet strip design in the head levels up the downforce and improves the protection of strings. TK-9900 is an ideal racket for aggressive players.
TECHNOLOGIES
The box-shaped design effectively increases stabilty and anti-torque allowing the racket to withstand higher string tensions.
The single-pass grommet hole construction creates less friction between strings effectively reducing tension loss while extending string durability.
Liquid Crystalline Polyester originating from Japan with interwoven braided layers quickly absorb vibration in order to enhance outstanding elasticity and stability during play.
Inspired by military helicopters, multi-layered structure made by carbon fibre and composites are used to minimize material size, reinforce handling feel and performance at a critical standard.
