The Li-Ning Air Stream N99 Special Limited Edition is used by World Champion and Olympic Gold Runner up Chen Long. The Li-Ning N99 is part of the "Air Stream System Series" which uses the wind tunnel structure which reduces wind drag by 8.2% and increase the shuttle speed by 3.1%. The iconic wind tunnel design minimize the formation of eddy during swinging motion. It prevents racket instability and also achieves more accurate dropping point. The N99 is an ideal racquet for drop shot technique play . With added weight to its racquet head using the latest Multi Polymer Carbon Fibre Reinforcing Technology, players can maximise the advantages of G Force, while optimise the gravity force to create exceptional power and speed. Through extensive research an development in Nano Science Technology, G Force provides players with the extra edge needed in their game. Frame Material : Carbon Fiber Shaft Flexibility: Medium Balance Point (Head Balance): 298mm Recommended Tension: 24 - 28 lbs
