Astrox 77 Pro: a title two days after release, then An Se-young’s two world crowns
A title two days after release
The Astrox 77 Pro went on sale worldwide on October 21, 2022, and won a Super 750 title two days later. At the Denmark Open, Fajar Alfian and Muhammad Rian Ardianto beat Marcus Fernaldi Gideon and Kevin Sanjaya Sukamuljo in a hard-fought all-Indonesian men’s doubles final, and Yonex Japan’s report noted that Alfian had won in his first event with the new racquet. The longer record belongs to An Se-young, whom Yonex lists on the 77 Pro for her first All England and for world titles in 2023 and 2026.
A softer 77, by design
Yonex announced the second-generation Astrox 77 on September 21, 2022, and turned the first one’s pitch around. The Astrox family’s head-heavy power usually takes strength to unlock, it said, while the new 77’s power was “effortless and accessible to all,” from a mid-flex shaft and “a maneuverable, slightly heavy head.” The Pro’s main change is Flex Fuse, a new resin in the joint at the bottom of the frame that Yonex Japan says is 11% softer than conventional resin, for a milder feel at impact. The shaft is high-modulus graphite with Namd and Ultra PE Fiber, finished with the Energy Boost Cap Plus, and the Rotational Generator System carries over from the first 77. Yonex claimed 2.9% more smash power than the original. The Pro is made in Japan, 10 mm longer than standard and rated medium flex, and it launched at ¥25,000 before tax.
An Se-young and the launch four
Yonex launched it with four players: Chen Yufei, An Se-young, Huang Yaqiong and Alfian. Yonex Japan lists An and Chen on the 77 Pro for the March 2023 All England final, which An won in 75 minutes for her first title there. In August 2023 she beat Carolina Marín, on the Nanoflare 1000 Z, for the world title in Copenhagen; Yonex Japan noted she was the first Korean, man or woman, to win a world singles title. Yonex published no equipment list for the Paris Olympics, but its lists and athlete pages show the 77 Pro for her in June and August 2024. In August 2026 in New Delhi she beat Akane Yamaguchi 21–17, 21–14 for a second world title, again listed on the 77 Pro. Chen won the 2023 French Open on it, and Huang took the 2023 and 2024 All England mixed doubles titles with Zheng Siwei. Huang’s 2022 world title and An’s 2021 World Tour Finals came earlier, on the first-generation 77.
Pro, Tour and Play in one orange
The second generation came in three tiers, all in High Orange in Yonex’s 2024 catalog: the Pro (item code AX77-P), the Tour (AX77-T) and the Hi-Flex Play (AX77-PL). Only the Pro has Flex Fuse in the frame and Namd in the shaft, and Yonex Japan sold only the Pro at launch. Against the 2017 Astrox 77 (code AX77, in Shine Yellow, Metallic Blue and later Shine Red), Yonex kept the medium flex, the 10 mm extra length and the 3U and 4U weights, replaced the frame’s Nanometric with Flex Fuse and added Ultra PE Fiber to the shaft. Yonex Japan’s Astrox list already showed the 77 Pro in place of the original in September 2022. Yonex Japan added the Taiwan-made 77 Tour to its line in April 2024 and a Light Beige design of it in March 2026, with the Pro still beside it; the Tour and the Play each have their own page.
Four years in production
The 77 Pro is still in production four years after launch and appears in Yonex Japan’s 2026 catalog, so new frames remain the main supply. The verified sales shown above are mostly pre-owned frames from the Asian resale market, with a few unused ones. It is a player’s racquet rather than a scarce one: a single standard colorway, made in volume and widely played. Its interest for collectors lies in its record, chiefly An Se-young’s, and that record belongs to the model. Yonex’s reports never name a colorway or a particular frame, so no example on the market can be tied to a title.
Same orange, different racquets
No counterfeit of the 77 Pro itself is documented. The only Astrox 77 fake documented in detail is a 2018 first-generation Shine Yellow frame, covered on the Astrox 77 page. Popular pro frames attract copies, though, and Yonex says counterfeits are difficult to tell from genuine racquets just by looking at them. It also says racquets bought through private sales, or whose purchase history cannot be confirmed, get no after-sales service. The likelier mistake is a mislabeled tier. The Pro, Tour and Play all wear High Orange (the Tour and Play also come in Light Beige since 2026), so an orange 77 is not necessarily a Pro, and the 2017 Astrox 77 shares the name. The item code and the Made in Japan marking settle it. The callout lists the checks.
An Se-young’s racquet
The 77 Pro’s place in Yonex’s history rests on An Se-young: an All England and two world titles on a racquet Yonex pitched as accessible rather than extreme. She is sometimes said to play the Nanoflare 1000 Z, the racquet Marín used in the 2023 final, but Yonex lists An on the 77 Pro. Yonex Japan’s results lists printed a plain “ASTROX 77” for her from March 2025 to mid-2026 without announcing any change, while its athlete pages kept the Pro, and its August 2026 list names the Pro again. Other users changed racquets around it. Alfian won the 2023 All England on the 77 Pro before switching to the 88 S Pro for 2024, and Kento Momota appears with both the 99 Pro and the 77 Pro in Yonex’s list for his fifth national title in December 2022.
Yonex’s item code is AX77-P. The 77 Pro is High Orange, marked Made in Japan, 10 mm longer than standard, medium flex, in 4U (average 83 g, grips 5–6) or 3U (average 88 g, grips 4–6). Yonex lists HM Graphite, Flex Fuse and tungsten in the frame and HM Graphite, Namd and Ultra PE Fiber in the shaft. The 77 Tour (AX77-T), which Yonex Japan lists as made in Taiwan, and the 77 Play (AX77-PL) also come in High Orange, so check the code and the origin marking. The 2017 Astrox 77 is code AX77, in Shine Yellow, Metallic Blue or Shine Red, with Nanometric in the frame. Yonex’s own test is the hologram sticker, which resists peeling on a genuine racquet and lifts easily with a fingernail on a fake.
The 77 Pro is current, so most buyers will choose new stock on weight and grip. For a pre-owned frame, ask for daylight photographs of the whole frame, the T-joint and the butt cap, and a visible AX77-P code. Yonex Japan rates it best for intermediate men and advanced women; it rates the ArcSaber 11 Pro best for advanced men. Its recommended tension is a range: 19–27 lb for 4U and 20–28 lb for 3U at launch, and 20–28 and 21–29 in Yonex’s 2024 catalog. Treat claims that a frame was match-used by An Se-young or Chen Yufei as unproven without documentation.
