Nanospeed 7000: the fullerene racquet that opened Yonex’s nanotech era
Sold out from the start
Yonex’s own history calls the Nanospeed 7000 the first badminton racquet to use nanotechnology. It went on sale in Japan in late November 2004, and Yonex remembers it as a hit: demand outran production, and the racquet was out of stock for several months. Its new ingredient was fullerene, a ball-shaped carbon molecule, which Yonex said let it make the carbon walls thinner while raising durability, overturning the idea that a thinner racquet had to be a weaker one. When the Nanospeed 8000 followed in April 2005, Yonex Japan introduced it as its second nanotech badminton racquet, so the 7000 is where Yonex’s nano line begins.
Speed of Science
Yonex Japan launched the 7000 under the line “Speed of Science,” saying it had turned to nanotechnology to keep pace with a faster, more powerful game. Its launch page described fullerene molecules 0.7 nanometers across placed between the carbon fibers to form a material it called Nano Carbon, and claimed 30% more impact strength, 10% more durability and 5% more rebound than conventional material. A Yonex Japan release of 2005 located it in the upper frame and the shaft. The racquet cost ¥21,000 before tax with a soft case, and Yonex described it as top-light, 10 mm longer than standard and made in Japan. The material is often called carbon nanotube, but Yonex’s pages say fullerene; Yonex introduced cup-stack carbon nanotube in 2007, with the first ArcSaber.
Gao Ling and a Korea Open title
Yonex ties two well-known players to the 7000, one more firmly than the other. Its 2017 anniversary page pictures China’s Gao Ling, the Athens 2004 mixed doubles champion, under the racquet, with a note dating her use to 2004. The racquet went on sale three months after Athens, though, and Yonex Japan’s staff page still listed her on the Muscle Power 90 in April 2005 and on the NS-7000 from that September. By January 2007 Yonex’s Korea Open report had her on the Nanospeed 9000 Type S. The firmer link is a title. The same report lists Jung Jae-sung on the Nanospeed 7000 when he and Lee Yong-dae, on the Armortec 800 Defensive, won the men’s doubles 21–16, 21–15 over Lee Jae-jin and Hwang Ji-man. No other documented Yonex tournament report of 2007–08 names the 7000.
Three finishes in seven years
Yonex sold one model, item code NS7000, in three Japanese finishes. The launch color was Bright Red (212), shown in Yonex’s ad with a silver and gold throat, and Yonex Japan lists its production as ending in 2006. A Deep Red version followed, ending in 2009, and a Pearl White/Red (636) went on sale in January 2010 and ended in 2011. Yonex gives all three the same 3U and 2U weights, the same recommended tension (19–24 lb for 3U, 20–25 lb for 2U) and Made in Japan, and the price stayed at ¥21,000 before tax. By 2010 Yonex Japan pitched it as an all-round model for intermediate and advanced players, strong in both attack and defense. Its export pages rated it Stiff throughout. Yonex made no player or limited edition.
A player’s frame, not a rarity
Verified sales of the NS-7000 so far are pre-owned frames from Asia resale across all three finishes, and the price panel above lists them. It was sold for a long time and in many markets. Yonex Japan sold it from November 2004 until production ended in 2011, Yonex USA listed it by October 2005, and Yonex’s global Nanospeed chart still showed it in April 2011, beside the 8000, the 9900 and a range of newer Nanospeeds. That long run means a frame offered as a 2004 original may be one of the later finishes, so the color tells a buyer more than the name does. Any unused frame is old stock at least fifteen years old.
Copies and mix-ups
No counterfeit report specific to the 7000 has been found. Nanospeed frames were copied early, though: a fake Nanospeed 8000 was identified on BadmintonCentral less than three months after that model’s launch, as the NS-8000 page describes, and a 2009 forum post named the 8000 and 9000 among the fakes most often met. With the 7000 the more frequent problem is identity. One name covers three finishes made over seven years, and the 8000 and the two 9000s that followed it also used fullerene, carry the Nanospeed name and were sold alongside it for years.
Where the nano line began
Yonex’s 2017 anniversary timeline uses the Nanospeed 7000 to stand for the start of its nanotechnology era, one of thirteen landmark racquets, placed between the Armortec 700 of 2003 and the ArcSaber Z-Slash of 2009. The line moved quickly from there. The Nanospeed 8000 of 2005 kept the fullerene but moved closer to even balance, the Nanospeed 9000 of 2006 added rubber metal to the frame sides, and the Nanospeed 9900 of 2009 put X-Fullerene in the frame. The ArcSaber range, meanwhile, brought carbon nanotube into Yonex’s frames. The 7000 outlasted the 8000’s first color and both 9000s in production, and Yonex Japan was still selling it in 2010.
Look for NANOSPEED 7000 printed along the shaft, as in Yonex’s launch ad, and the item code NS7000. Yonex documents three finishes, Bright Red (212), Deep Red and Pearl White/Red (636), all made in Japan, in 3U (85–89.9 g) or 2U (90–94.9 g), never 4U. Yonex rates it Stiff with a top-light balance and a frame 10 mm longer than standard. There is no player or limited edition, so a player’s name on a frame is not Yonex’s. Yonex’s counterfeit guidance of the period gives general checks: a hologram sticker, if present, should resist peeling; the O in YONEX should be narrow, not wide and round; the production code on the cap above the handle should be laser-engraved; and the butt cap should match Yonex’s green.
The NS-7000 matters as the start of Yonex’s nanotechnology line, and its documented court record is modest: a 2007 Korea Open title for Jung Jae-sung and a staff-page listing for Gao Ling. Buy it as a playable Japan-made frame, choose the finish you want, and judge it on the condition of the head, grommets and joint. It pairs naturally with the NS-8000 and the two Nanospeed 9000s for the line’s first years.
