Astrox 100 ZZ: the Hyper Slim flagship behind Axelsen’s two Olympic golds
Two Olympic golds on one frame
Viktor Axelsen won Olympic gold in Tokyo in 2021 and again in Paris in 2024 with the Astrox 100 ZZ, a frame he took into competition before it was on sale. Yonex built it around a Hyper Slim Shaft that it called the slimmest in its history and placed it at the top of the Astrox power line. Yonex also named Akane Yamaguchi as a launch user, and its athlete pages now list both 2025 singles world champions, Yamaguchi and Shi Yuqi, on the 100 ZZ. In 2025 Yonex gave Axelsen his own version, the Astrox 100 VA edition. The standard 100 ZZ has no announced end date, and its Kurenai colorway was still in Yonex’s global catalog in 2026.
March 2020 and the Hyper Slim Shaft
Yonex announced the Astrox 100 ZZ and its sibling, the Astrox 100 ZX, in February 2020 and released both on March 20 in Dark Navy, in 3U (average 88 g) and 4U (average 83 g). The Japanese price for the ZZ was ¥28,000 plus tax. Yonex separated the two by frame material and shaft: the ZZ has Black Micro Core in the frame and a solid Hyper Slim Shaft, the ZX Nanomesh Neo in the frame and an Extra Slim Rexis shaft. The ZZ frame combines HM Graphite, Namd, Tungsten, Black Micro Core and Nanometric, with an Extra Stiff shaft, a frame 10 mm longer than Yonex’s standard, and the Rotational Generator System, which places mass at the frame top, T-joint and grip end. The launch figures, including 11.8% less air resistance and a 2.9% larger sweet spot, are Yonex’s own claims.
Axelsen, from Birmingham to Paris
Axelsen won the 2020 All England on March 15, beating Chou Tien-chen 21–13, 21–14, five days before the 100 ZZ and ZX went on sale. Yonex’s English report called it his debut with “the Astrox 100” without naming a model, but Yonex Japan’s report two days later is headed with the Astrox 100 ZZ and lists it as his racquet. Yonex’s equipment lists name it for him again at the March 2021 All England and at the end of 2021. In between came Tokyo gold on August 2, 2021, 21–15, 21–12 over Chen Long. He added the 2022 world title, three straight World Tour Finals from 2021 to 2023, and a second Olympic gold in Paris on August 5, 2024, 21–11, 21–11 over Kunlavut Vitidsarn. Some retail listings credit Paris to the VA edition, which Yonex did not announce until March 2025. Axelsen retired in April 2026, citing back problems. Yamaguchi won world titles in 2021, 2022 and 2025; when she moved to the 100 ZZ is undocumented.
Colorways, regional editions and namesakes
Dark Navy was the launch finish. Kurenai, Japanese for crimson, followed in late May 2021 with identical published specifications. Many retailers call Kurenai a limited edition, but Yonex promoted it as a new colorway alongside the classic Dark Navy, and five years later it was the one still in Yonex’s global catalog. Dealers also sell two region-specific finishes on the ZZ frame: a black-and-purple “BP” described as a Japan-domestic exclusive, and a red “China Win” national-team edition sold in China, including as a gift set. Yonex has published no release dates or production figures for either. The Astrox 100 VA edition (item code AX100VAZ) followed in Grayish Beige in September 2025. The Astrox 100 ZX, 100 Tour and 100 Game are separate, cheaper models rather than ZZ colorways, and the Tour and Game were also sold in Kurenai.
What the verified sales cover
The verified sales shown above are eBay sales of new, unstrung Dark Navy frames. Most have cleared above Yonex’s current US list price, with one noticeably weaker month. Nothing verified yet covers Kurenai, the regional finishes or the VA edition. Two points matter when reading these figures. Dark Navy has dropped out of Yonex’s global catalog while the physically identical Kurenai stayed, so a premium for navy is a premium for the color alone. And for the BP and China Win finishes, dealer asking prices are the only figures in circulation; an asking price is not a market value, and none of those finishes has a verified sale here.
Why mislistings cluster here
Counterfeiters target the ZZ because it is Yonex’s best-known power frame and is tied to Axelsen’s titles, but the more common problem is the name. The Astrox 100 ZX launched the same day in the same Dark Navy, and Yonex Japan’s release lists it as Taiwan-made. The 100 Tour and 100 Game followed in 2021, sold only in Kurenai, and Yonex Japan lists both as made in Taiwan; each has its own page. A seller can list any of them as a “100 ZZ” without faking anything, and in photographs they are hard to separate. The practical checks are the ZZ marking, a Japanese country of origin and the shaft itself, which retailers list at 6.2 mm on the ZZ against 6.7 mm on the Tour. The VA edition adds confusion of its own, because Yonex’s regional sites disagree about its materials.
The VA edition and an open ending
Yonex made Axelsen a signature athlete in March 2025, alongside Lin Dan and Lee Chong Wei, and set September 26, 2025 as the global launch of its collection, including the Astrox 100 VA edition, with a personal letter from Axelsen enclosed in the first 10,000 racquets. Yonex’s global and US pages give the VA the same frame materials and Extra Stiff flex as the standard ZZ; its Far East page lists Volume Cut Resin, a Stiff flex and an Extra Slim Shaft instead. Yonex describes the collection’s racquets as special-edition designs based on its existing models, and its Japanese listing matches the standard ZZ, so the Far East row reads as data borrowed from other models. The standard ZZ has no announced end date. Dark Navy has left Yonex’s global catalog, and Kurenai is still sold.
Dark Navy, Kurenai and the VA edition are all made in Japan, so a “100 ZZ” marked Taiwan or China is a 100 ZX, Tour or Game, or a fake. Yonex’s own test is the hologram sticker, which should resist lifting with a fingernail. Retailer guides add that genuine serial numbers are laser-engraved as well as printed, and that the butt cap should be Yonex’s standard green with a cleanly formed logo. Then check the specification: Yonex gives Extra Stiff flex, a 22 x 21 string pattern, a frame 10 mm longer than standard and an average of 83 g for 4U. Retailers list the Hyper Slim shaft at 6.2 mm and 76 grommets, so a visibly thicker shaft on a frame badged ZZ is a red flag. Yonex USA’s advice is to buy from authorized retailers and contact its customer support if unsure.
For players, Kurenai and Dark Navy are the same racquet, so any premium on navy buys only the color. For collectors, the ZZ’s interest lies in Axelsen’s years on it, from the 2020 All England to Paris, and in the standard frame that preceded his signature edition. Dealers describe the BP and China Win finishes as limited, but Yonex has published no production figures and there are no verified sales for either, so a buyer has only dealer descriptions to go on. Check any “100 ZZ” listing against the ZX, Tour and Game before anything else.
