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

 

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

 

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

 

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

    This is a very good racket if you love being a dominant smashing player. The racket is quite head heavy and it is good choice for strong attacking.

    Happy with the purchase, rackets arrived in perfect shape, I had my rackets stringing done by Chris many time and it’s been excellent.
