1
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

2
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.
3
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

4
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

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.
