Quick Answer: Most Durable Badminton String

On Yonex's own rating scale, Exbolt 68 has the highest published durability rating in the reviewed 2026 range (11), one point above BG65 (10). Gauge alone does not decide it. And if you keep breaking strings, tension, shuttle type and grommets usually matter more than the name on the reel.

Exbolt 68

Best choice: durability 11 at 0.68 mm, with control rated 10 and repulsion 9. The pick if you break strings and do not want to give up feel.

BG65

Durability 10 at 0.70 mm; repulsion rated 7 and sound, shock absorption and control rated 6. The soft, forgiving workhorse when string life matters more than feel.

VBS-70

Victor's durability string, 0.70 mm with a soft feel. Victor publishes no number, so VBS-70 against VBS-69N is a feel decision, not a durability one.

Not on the list: BG65 Titanium. It shares BG65's gauge and core, but Yonex rates its durability 7, not 10.

Compare manufacturer durability ratings alongside string construction, tension and your own break history. Ratings are useful within a brand’s system; they are not measured guarantees of sessions or months.

Durability on the makers' own scale

Yonex publishes five attribute ratings for the strings below: repulsion, durability, hitting sound, shock absorption and control. These are manufacturer comparisons, not a universal laboratory scale; ratings elsewhere in the catalogue extend below 6.

Yonex string Gauge Yonex family Durability Repulsion Control
Exbolt 68 0.68 mm Durability 11 9 10
BG65 0.70 mm Durability 10 7 6
Exbolt 65 0.65 mm Quick Repulsion 8 10 10
BG65 Titanium 0.70 mm Durability 7 7 6
BG80 Power 0.68 mm Quick Repulsion 7 9 6
Exbolt 63 0.63 mm Quick Repulsion 7 11 10
Aerobite Boost 0.72 / 0.61 mm Control 7 8 10
BG80 0.68 mm Quick Repulsion 6 8 6
BG66 Ultimax 0.65 mm Quick Repulsion 6 10 10
BG66 Force 0.65 mm Quick Repulsion 6 10 10
Aerobite 0.67 / 0.61 mm Control 6 10 10

Victor sorts its strings into three categories instead of scoring them, and each product page lists gauge and feel. From Victor's own string guide and its product pages:

Victor string Gauge Victor category Feel (Victor's word)
VBS-70 0.70 mm Durability Soft; "perfect for all types of players"
VBS-69N 0.69 mm Durability Slightly firmer than VBS-70; for attacking players
VBS-68 Power 0.68 mm Control Soft; longer contact time
VBS-68 0.68 mm Control Hard
VBS-66N 0.66 mm High Resilience Medium
VBS-61 0.61 mm Not stated Not stated
VBS-58N 0.58 mm Not stated Medium

This table covers the Yonex and Victor specifications reviewed for this guide; it does not rank all manufacturers.

Gauge is not what decides durability

Read the Yonex table against the thicker-is-tougher rule and it fails three times in one lineup:

  • Exbolt 68 at 0.68 mm rates above BG65 at 0.70 mm on Yonex's scale, 11 to 10, while scoring 10 for control against BG65's 6.
  • Exbolt 65 at 0.65 mm is rated 8, above BG80 at 0.68 mm (6) and above BG80 Power at the same 0.68 mm (7).
  • Aerobite Boost carries the thickest main string Yonex makes, 0.72 mm, and is rated 7. BG65 Titanium has BG65's gauge and BG65's core but has a lower published durability rating.

Gauge is one factor in wear resistance, alongside the core, outer braid, coating and stringing conditions. A thicker string of similar construction may resist abrasion longer, but gauge alone cannot rank different models.

Use the manufacturer’s durability category as a starting point, then compare your own sessions and wear pattern at a consistent setup.

The shortlist for string breakers

Four strings are worth a string breaker's next restring. The right one depends on how much feel you are willing to trade for string life.

String Durability (maker) What you give up Choose it if
Yonex Exbolt 68 11 of 11 Shock absorption is rated 6; try its feel at your chosen tension. You break strings and want to keep control (10) and most of your repulsion (9).
Yonex BG65 10 of 11 Repulsion, sound and control all sit at 6; it feels plain next to anything thinner. You want a durability-focused starting point and a soft hitting feel.
Victor VBS-70 Victor's Durability category, no number Soft feel; less crisp on flat exchanges. Your stringer carries Victor, or you play a Victor frame and want the matching string.
Yonex Exbolt 65 8 of 11 Three points of durability against Exbolt 68. You want a repulsion rating of 10 with a higher durability rating than the listed BG80 and BG66 models.

What to skip if string life is the problem

BG80, BG66 Ultimax, BG66 Force and Aerobite are all rated 6 for durability. A durability-focused alternative may suit frequent string breakers, but inspect the cause before changing models. BG65 Titanium is rated 7 and described with a sharper hitting feel. The head-to-heads are in BG65 vs BG66 Ultimax vs Aerobite, and the whole Yonex, Victor and Li-Ning map is in how to choose badminton strings.

Nanogy 95 is not listed in the 2026 international catalogue used here; regional listings and remaining stock can differ.

Why your strings actually break

Central wear, frame-edge breaks and damaged grommets give a stringer different clues, but the break site alone is not a diagnosis.
Central wear, frame-edge breaks and damaged grommets give a stringer different clues, but the break site alone is not a diagnosis.

A string that snaps in the centre of the bed after weeks of notching is a different event from one that goes at the frame in its second session, and swapping reels fixes only one of them. Before you cut the old strings out, look at where the break is and what the string looks like on either side of it. The table gives the most likely reading for each pattern; it is a starting point, not a verdict.

Where and when it broke Most likely cause The one change to make
Centre of the bed, after weeks of play, crossings visibly notched Normal wear. The string reached the end of its life. Nothing is wrong. Move up the durability column if you want more sessions per restring.
Centre of the bed, within the first few sessions, no notching Tension too high for the string, the racket or your shuttle, or a stringing fault such as a kinked or over-clamped string. Tell the stringer about the early break; inspect the setup before trying a small tension reduction.
At the frame, top of the head, string looks cut or shaved Possible off-centre contact, damaged grommet or stringing damage; location alone cannot identify the cause. Check the grommets and stringing first, then review spacing if off-centre contacts repeat.
At the frame, side or bottom, string flattened or frayed inside the hole A split, sunken or missing grommet letting the frame edge bite the string. Replace the grommets before the next restring. Same string, same tension.
Anywhere, but only on nylon-shuttle nights A change in shuttle or hitting conditions that warrants comparing the break pattern. Discuss the shuttle model and trial a modest tension change if needed, within the frame’s guidance.

Photograph the break site before the strings are cut, then follow your stringer’s advice promptly. Record sessions as well as elapsed time; an unused string bed can still lose tension.

For the finer clues, including shared-hole breaks and how to avoid over-calling a mishit, read the string break location guide. If the frame is doing the damage, the grommet replacement guide shows what a failed grommet looks like and when a stringer should replace the strip.

Tension: the second lever

Higher tension can make a string bed less tolerant of off-centre contact, but lifespan also depends on stringing quality, wear, grommets and play. There is no reliable sessions-per-pound conversion.

Do not assume a short clear or a dull feel calls for more tension. Check contact quality and the condition of the string bed, then change one setup variable at the next restring.

  • Stay inside the range printed on your racket. Above it, you are stressing the frame and the string together, and most brands treat it as a warranty question.
  • Drop before you switch. If equipment checks do not explain early breaks, try a small tension reduction at the next restring and record the result.

What each tension from 20 to 30 lbs feels like, in lbs and kg, is in the string tension guide.

A change-one-thing plan for your next four restrings

The following trial keeps a record of string, tension, shuttle type and sessions per restring so you can compare like with like.

Restring Change exactly this What you learn
1 Grommets checked and replaced if any are split or sunken. Same string, same tension as before. Whether the frame was cutting the string. An improvement suggests the grommets contributed.
2 Switch to Exbolt 68, BG65 or VBS-70. Same tension. How much of the problem was the string. Compare actual sessions rather than predicting the gain from the rating.
3 Same string, a small tension reduction agreed with the stringer. Whether tension was doing the damage. If the bed now feels dead, go back up 1 lb next time; if it lasts and feels fine, stay.
4 Nothing. Repeat the best setup and count again. Whether the result holds. If it does, that is your setup; write it down and stop experimenting. If breaks still cluster at the frame, recheck equipment and off-centre contacts.

Four restrings sounds slow, but a breaker is restringing that often anyway. The difference is that at the end you know why, and the next racket you buy gets strung right the first time. How often to restring gives the normal intervals to measure yourself against.

What changes for Canadian club players

Canadian clubs use both nylon and feather shuttles. Tell your stringer which model you use, and consider a modest tension trial only if your current setup feels harsh or breaks early; there is no universal 2–3 lb correction.

Store the racket indoors and avoid prolonged temperature extremes. A break after cold storage still needs the same inspection for worn strings, mishits, grommets and stringing damage.

FAQ

What is the most durable badminton string?

On Yonex's published scale, Exbolt 68, rated 11, with BG65 second at 10. Victor puts VBS-70 and VBS-69N in its Durability category but publishes no figure, so they cannot be ranked against Yonex.

Is BG65 Titanium more durable than BG65?

Yonex’s 2026 catalogue rates BG65 Titanium 7 and BG65 10 for durability, while both have repulsion rated 7. These ordinal ratings do not establish a percentage or number of sessions lost.

Does a thicker string always last longer?

Not across models. Exbolt 68 (0.68 mm) is rated above BG65 (0.70 mm), and Exbolt 65 (0.65 mm) above BG80 (0.68 mm). Gauge helps only when the construction is the same.

Is Yonex Nanogy 95 still available?

It is absent from the 2026 international catalogue reviewed here. Regional availability can differ; check the exact current listing.

How many sessions should a string last?

Track your own sessions and inspect the string bed rather than relying on a fixed calendar interval. Frequent early breaks warrant checking the break site and setup.

Does cold weather make badminton strings brittle?

Storage conditions alone do not establish why a string broke. Avoid prolonged temperature extremes and inspect the break site, grommets and string condition.

Which durable string should you choose?

  • Choose Exbolt 68 if you break strings and want to keep control and most of your repulsion. Highest durability figure Yonex publishes.
  • Choose BG65 if you want a durability-focused string with a soft hitting feel.
  • Choose Victor VBS-70 or VBS-69N if you play Victor or your stringer carries Victor; VBS-69N is the slightly firmer of the two.
  • Choose Exbolt 65 if a repulsion rating of 10 is non-negotiable and you accept a durability of 8.
  • Skip BG65 Titanium, BG80, BG66 Ultimax and Aerobite until the breaking stops; all are rated 7 or lower.
  • Before any of that, check the grommets, record the break site and discuss string, tension and shuttle type together.
