Overview
First-gen Astrox 99 Pro (second Astrox 99-family generation) — includes Sun Orange colourway notes. See gen-2 and gen-3 deep dives for later Pro revisions. Generation context: The original Astrox 99 (2018, no "Pro" suffix) was the first Astrox 99-family frame. Astrox 99 Pro arrived as the second family generation — and this article covers that first Astrox 99 Pro revision (often called gen-1 99 Pro). Only the second and third Astrox 99 Pro generations carry "Pro" in the name; gen-2 and gen-3 deep dives live on sibling URLs. Sometimes I regret never getting proper coaching — my level is not enough to unlock everything certain rackets offer. Thanks to the community for sharing experience. Specs: 4U G5, heat-shrink wrap on, strung weight 96.0 g, balance 299 mm, NAMD shaft 210 mm, tuned stiff, E-CAP cone, fish-mouth 4 mm, 5–7 grooves, box frame, 28 lb warranty, strung 26–27 lbs VBS68. Looks need little comment. Astrox 99 Pro feels very head-heavy from pick-up. Balance under 300 mm is only because the handle is weighted — with my usual cap-removed setup I would expect balance around 315 mm. Even in 4U it gave me strong Dragon Fang vibes. Unless I am fresh and committed to mixed doubles against weaker opponents, this racket is almost useless to me as a non-singles player. In doubles, head weight and high drag still slow swing speed in fast exchanges — mishits and rhythm errors follow. Beyond swing speed lies another debate: the 68-hole string bed. More holes usually mean denser bed, harder and more direct feel. First time on 68 holes for me — Astrox 99 Pro is not the hold-heavy bed general rules predict. It matches 80-hole hardness. Per Panghu’s breakdown, adjusted string spacing packs the sweet-zone mains and crosses tighter, pushing effective tension higher. High-tension durability was not proven in my trial, but forgiveness is genuinely poor. Without long break-in I kept mishitting; beginners would struggle more. Watch Momota and Lee Zii Jia’s unforced-error rates after switching to 99 Pro — draw your own conclusion. The racket is also very stiff — discouraging for injured, weak, or careless players. I even found Lee/Yonex’s older Tri-Voltage system softer. On prepared feed balls the stiffness hides — good elasticity plus head weight makes it feel workable. In live play I remembered conquering the DZS. Sweet-spot hits are crisp but power transfer feels incomplete. Before adaptation every swing felt like hitting a fire stick with no shaft bend. Ultra-stiff setup punishes rushed, panicked full swings with harsh feedback. By trial’s end my goal dropped from mastering it to landing one satisfying full smash. Until then I could bully weaker opponents with light kills, taps, and flat lifts using its excellent direction and stability — and that was it. First Astrox where Rotational Generator System felt useless to me — zero chain benefit in my hands. Chronic head weight means even old-colour 88D sets up faster. In doubles defence and flat-drive chains, if reflexes lag you are basically done. Do not expect net chances to save you — closer to the tape, the easier it is to wreck prep and swing rhythm, leading to whiffs, mishits, nets, and out balls. Contact point needs long adaptation; keep your temper. If defence chains usually lose, low backhand or body-line shots when tired were straight give-ups — swing incomplete, output weak, confidence shredded. Skill gap laid bare. Others speed-run Sekiro to Isshin; my run ended at the first general. What else is there to say? Not a racket built for me. I tried; some gear just will not click. On 99 Pro doubles nights I dropped wolfish net intercepts and pushes for soft blocks and drops I am bad at; I dropped reckless rear smashes and drives for taps and net turns. Every clear or slice-drop left me wanting one more session with perfect body state to force 99 Pro’s potential out once. Near return date I was finally improving — then, when I believed I could unleash its precise violence in full-send mode, I quit mentally. Technique and current body condition no longer allow new injuries.
Sun Orange colourway (original Astrox 99)
Many players attach extra meaning to the Sun Orange Astrox 99 — often tied to Kento Momota's era. That colourway sits on the pre-Pro Astrox 99 line (second Astrox 99-family generation overall, before the 99 Pro naming split). Specs (Sun Orange unit): 4U G5, cap removed, in use 90.6 g, balance 306 mm, shaft 215 mm, fish-mouth cone 3 mm, stiff tuning, 76 holes, box frame, 28 lb warranty, strung 26–28 lbs EXBOLT 63. I had tried the LCW colour and assumed tuning matched. Sun Orange feels slightly heavier in the hand and slower on empty swings — warm-up contact is firmer, with less shaft flex than LCW. Rear-court drives combine head-heavy balance and the fish-mouth cone's effective shaft length: obvious borrow and drive, hot shuttle in quick exchanges. Pre-100ZZ Astrox sweet spots were famously forgiving; NAMD stores extra energy after bed deformation for fast, heavy exits. Even in 4U, swing weight stays manageable — with decent technique, first impressions are strong. Unlike LCW, which I would still take into doubles, Sun Orange is basically a singles racket. Flat drives never quite reach pace in doubles; high swing weight makes drives clumsy in flat exchanges. Small flicks demand serious finger and wrist strength even in 4U. I mostly tested in doubles — avoid grinds, lift early, reset. What it returns is shuttle feel: solid, stable, trustworthy. For shot control I rank 88D and 99 at the top of the Astrox family. In hand, Sun Orange makes you want to own net or baseline — excellent anti-torsion plus NAMD's stress behaviour. At moderate power the bed wraps the shuttle just enough for fine adjustments; net spins stay tight and successful where older ZSP frames ballooned. Full smash: not everyone can weaponize it. Head-heavy downforce rivals VT80, Voltric ZF, and ZF2 with lower swing weight — less stamina tax, stricter power demand. NAMD rewards real burst; without it, heavy swings can feel dead. With burst, smashes are heavy and driven — anti-torsion and direction make the attack case undeniable. Passive defence beats ZF2 helplessness — soft blocks and borrowed rebounds work. Aside from slower swing and extra wrist load, no glaring weak spot.
