Li-Ning L69 string review: balanced at 25 lb, crisper once you pull it tight
Li-Ning L69 is a China-made 0.69 mm nylon with a spiral braid. At 25 lb it stays stable and muted; at 27–28 lb on a stiff frame it starts to bite.

Overview
"I can name a whole crowd who would rather save face than save money." "Won't touch staple string under 20 yuan." "Yonex is too expensive — Li-Ning has no substitute — Victor feel is wrong." (Guilty on all counts.) This one is for that tribe: Li-Ning — face value, price, playability. Week-long deep testing on L64, L67Q, and L69 — high-rep, balanced, durable covered. I stepped on the mines so you do not have to. (Some sub-20 yuan no-name lines are rough too — post still worth it — and it helps demystify Yonex a little.) Thanks to the forum trial and Li-Ning official for backing the session.
Setup
- Astrox 99 Pro: Li-Ning L69 - Astrox 99 Tour: Li-Ning L64 - Astrox 99 Game: Li-Ning L67Q All cap-removed 4U G5, 28 lbs, Yonex four-knot pattern. I am basically a 68-hole person — if a string works there, it usually works elsewhere.
L69 first
Excellent durable string — worthy of Li-Ning’s 2026 drop. My staple above 28 lbs is BG65 Ti, so I talk durability with some authority. Official label says balanced; in hand it leans durable. Last Li-Ning line I tried was No. 5 — weird feel, cut immediately. Early Li-Ning strings felt as wooden as their old shafts. This batch surprised me. Tuning is sharp. 0.69 mm on 68 holes is not dead — clearly ahead of BG65 Ti. I am considering full replacement. Spare Nanoflare 7 still on BG65 Ti at home — swap tests, L69 wins. Feel runs firm; output is not draggy. Singles and doubles can buy blind. More dwell and control lovers may feel short. In hand, L69 — thickest of the three — has the finest braid texture. Three days post-stringing, tension hold is solid — not the one-day-one-feel drama of No. 1 and No. 5. Forced pick among three? L69 — best value-to-feel ratio. (Still sounds brief? Keep reading.)
L67Q
Tried old L67 at 19 yuan — absurd durability, racket died before string. "Big thick guy" vibe, feel mediocre. L67Q now 17 yuan (so my 19 yuan was what, exactly?). L67Q swings faster — maybe head games — but feel beats old L67. Still vague overall; control trails L69 (hard act to follow). First hit whether you live on EXBOLT 63, BG65, or BG80 will not shock you. 48 hours in, feel turns woodier; swing character slides back toward L67. Not blind-buy tier — spend 3–4 yuan more for L69. Tuning and control sit a hair under BG65 Ti. You know the drill. Last thin-string era was EXBOLT 63 and Aerobite — played them, hype deflated, not magic. Bottom line: Li-Ning’s string game is legit now.
L64 — the split opinion
L64 vibrates more. I love it — big hit, that buzz~ — mates call it harsh. Subjective; skip if you hate feedback. Feel ~90% EXBOLT 63, moderate-firm. Tension hold beats L67Q, but thin gauge means drop hits harder than on durable lines. 72 hours: woodier but acceptable; hold slightly behind N65 and EXBOLT 63. Still excellent at this price — blind buy for me.
Bundled GP100 Pro grip (trial pack)
~25 yuan for three — not screaming value. Sweat absorption and grip are good; not tacky-soft — more tough and dry. Weird at first; light sweat later helps. I would buy other grips. Chalk-plus-towel-grip person speaking.
Stringing notes
Packaging labels L69 as durable-balanced — I side-eyed it on an offensive frame where I usually run BG80 or EXBOLT 63. My stringer pushed back: treat tension and pattern as seriously as the string itself. Before mounting, a good stringer will ask tension, two-knot vs four-knot, pre-stretch, and whether mains and crosses match or differ. That checklist matters on L69 — the line runs relatively firm and crisp, so sloppy jobs show up fast as early tension loss or wandering mains. On a 4U G5 Astrox 99 at 27 lb, four-knot, even tension, L69 surprised me: smashes knife-sharp with a satisfying tone — closer to what I want from an attack setup than the "durable line" label suggests. Early clear drills feel firm and direct; front court is excellent; heavy and tap smashes both pop harder than my old BG66N setup. String and stringer share credit — a clean four-knot job lets L69 punch above its durable billing.
Control and durability notes (Jun 2026)
Quick verdict first: among domestic strings at the thickest marketed gauge, L69 punches above its price — durable, little movement, decent elasticity and sound, firm jacket, slightly less spring than BG80. Control: the rough jacket adds friction on contact, so placement feels trustworthy. At high tension (I run 28 lb with 5% pre-stretch) control steps up again — reverse slices, chop drops, forehand slices and transitions all show the grip you want from a textured coat. Durability: the standout balanced trait. 0.69 mm plus a thick jacket survives high-tension matches without frequent breaks, and the coarse wrap reduces main movement — fewer single-string mis-hits. Rebound: do not expect thin-string fireworks. The thick jacket caps elasticity, but sweet-spot compression is obvious — at very high tension the bed can feel board-stiff; I recommend staying a pound or two under your BG80 number. Sound: at 28 lb pre-stretched 5% the tone is muted-steel on average hits, like clapping inside a quilt on full sweet-spot crushes. Net spins skew clearer. Feedback: vibration sits mid-high for the gauge — you always know where on the bed you struck, with strong location sense and no harsh hand sting. Good trade for control players who still want punch.
What the sheet says
L69 is AXJV033. The 2026 Li-Ning gear list prices a 10 m set at 38 yuan and dates the launch to January 2026, with a 200 m reel next to it. Gauge 0.69 mm, nylon, made in China, type marked well balanced. The construction note that shows up on the retailer sheet is a symmetrical spiral braid, which is what you feel as an even bed rather than a special coating. One pack chart I have seen scores durability 9, repulsion 8, and control, shock, and sound at 7. That is a marketing card. It is also a fair sketch of the string. I went looking for a hydrogenated titanium coat, because the muted tone reminded me of BG65 Ti. It is not on the spec sheet. The thicker gauge is enough to explain the sound. Do not buy L69 as a titanium string.
Tension changes the string
At 25 lb, about 20 hours of doubles in a week, the bed barely dropped, the mains barely walked, and the jacket did not fuzz. Sound is a thick knock, closer to a muffled pop than to BG95's crack, and the repulsion is the useful kind: a passive clear still reaches, and a smash does not float. Power transfer felt more direct than BG95 at the same tension, which is the opposite of what the price suggests. At 26 lb, four knots, even tension, on an AxForce Cannon, the feel is firm without being harsh. This is where L69 is a counterattack string. Blocks and receive-kills are the best shots on it. You can steer a lift, and a soft block finds a gap, because the bed is stable and the feedback does not wander from Monday to Sunday the way BG95 does after its first good week. Smash pace is yours. The string does not add a gear. Doubles that live on flat drives and a shared attack suit it. Doubles that need the string to supply a steep finish will feel under-gunned. At 27–28 lb on a stiff attack frame the same string wakes up. That is the session already above: on a 4U Astrox 99 the smash gets a sharper edge and a cleaner tone, and the "durable balanced" label starts to look timid. The extra tension is doing that work. If you want the lively version, string it a pound under your BG80 number rather than at a soft practice tension. If you want the stable version, 25–26 lb is the one that matched the card. After roughly 24 hours the sweet-spot jacket on one set was still intact, and the feel on a fresh bed and a settled bed stayed in the same place. That consistency is the reason I would take it over BG95 even when BG95 sounds prettier on day one. Spin on drops and slices is real. The jacket is smoother than I expected for that much bite, and it still holds the shuttle long enough to be useful.
Verdict
L69 is the balanced 0.69 mm it says it is, until you pull it tight. At 25–26 lb I get durability, a stable bed, and a thick, controlled hit. At 27–28 lb on a stiff frame I get a crisper attack string that still does not die in a week. China list is 38 yuan. That is the right money for a string I can leave on a match racket and also on the practice frame.
