The racquet that won Wimbledon, the Wilson nSix-One Tour 90, became world famous almost immediately after its launch.While we first witnessed professional players such as Roger Federer using the nCoded racquets at the French Open, it was at Wimbledon where Wilson's latest flagship player's racquet was thrust into the limelight. As Federer skillfully wielded his nSix-One Tour 90 to dispatch all-comers and defend his Wimbledon title, we got a good look at the latest offering from Wilson to take the racquet world by storm.Federer's racquet of choice, the nSix-One Tour 90, retains much of the same design as the Pro Staff Tour 90 that it replaces. The same 17mm straight box-beam design, headsize, leather grip, and 9 points head light balance are retained. Gone is the predominantly black look and textured paint around the upper hoop. Instead, the nSix-One Tour 90 features the bright red and white used throughout the nCode line. More importantly, it is under the paint where the most significant modification occurs. The nSix-One Tour 90's main technological feature is Wilson's nCode construction process.The nCode construction process adds material to the frame at the nano level. According to Wilson, in an nCoded racquet, nano-sized silicone crystals permeate the voids between the carbon fibers. Wilson claims that their exclusive nano technology creates racquets that are two times stronger, two times more stable and up to 22% more powerful than ordinary racquets.To see if the nCode technology could meet our tennis needs, we hit the courts with the nSix-One Tour 90 for a three-week playtest. Read on to find out if our playtesters were able to unlock their potential.Before hitting the courts we strung the nSix-One Tour 90 with Wilson NXT 17 string at 57lbs (2 lbs above mid recommended tension).
