Description

rotational generator system

QUICK BENEFIT

Continuous powerful attacks

PROPERTIES

Weight is distributed throughout the grip end, frame top and the joint for continued powerful attacks
POWER-ASSIST BUMPER adds weight to the frame top, enhancing power transfer to the shuttle while reducing air resistance
The LIGHTWEIGHT END CAP enables an extremely head-heavy weight distribution

RESULT

Enhanced Rotational Generator System guiding smooth transitions from shot to shot

Slide 2 of 5: 2G Namd Flex Force. QUICK BENEFIT Uncompromised shot power and increased shot information PROPERTIES Graphite characterized by its quick flex and snapback. The Carbon Nanotube binding the graphite together reduces energy loss and enhances its resilience. RESULT Used in the whole racquet, the rapid flex and snapback allows more shuttle hold to feel the shuttle and transmit maximum power. *Used in PRO/TOUR models *Namdis technology developed by Nitta Co., Ltd. to uniformly disperse carbon nanotubes in carbon fiber composites.

LIGHTWEIGHT END CAP

QUICK BENEFIT

Increased power

PROPERTIES

A newly designed end cap which is made lighter by removing the weight inside

RESULT

Balance is shifted towards the racquet head, making this model the most head-heavy racquet within the current line-up

Slide 4 of 5: CONCENTRATED SWEET SPOT FOR POWER. QUICK BENEFIT Increased shot power PROPERTIES Concentrating power to the sweet spot by revising the frame shape. RESULT Meeting the demand of heavy smashers with an increased shot power

CONCENTRATED SWEET SPOT FOR POWER

QUICK BENEFIT

Increased shot power

PROPERTIES

Concentrating power to the sweet spot by revising the frame shape.

RESULT

Meeting the demand of heavy smashers with an increased shot power

Slide 5 of 5: SHOT INFORMATION CONNECTOR. QUICK BENEFIT Increased shot information PROPERTIES Weight is concentrated in the racquet head by taking out weight from the shaft and end cap to increase flex The ANTI-TORSION SHAFT using high rigidity graphiteis designed to lower the torque, keeping the racquet face straight RESULT Provides confidence with increased shot information by extending contact time between the shuttle and the string to transfer information without loss
