Li-Ning No 1 Boost Badminton String

God of Sports Expert Verdict on Li-Ning No 1 Boost Badminton String:

• Li-Ning No 1 Boost Badminton String is the most practically useful member of the No. 1 family for the majority of Indian intermediate to advanced club players. It takes the original No. 1’s repulsion credentials — China National Team pedigree, 0.65–0.66mm performance tier, high-intensity nylon construction — and makes them more accessible through two targeted construction upgrades: a nano-braided core for better internal consistency, and a compound elastic resin coating for softer feel and meaningfully better durability. The result is a string that delivers equal or higher repulsion to the original with a more forgiving feel and longer lifespan.
• The feel difference between No. 1 Boost and original No. 1 is real and significant for many players. The original No. 1 is hard — distinctly hard, in the way that professional players who grew up on control strings describe it as demanding. The Boost’s elastic resin coating creates a perceptibly softer, slightly more elastic contact that cushions the hardness without eliminating the repulsion. Expert reviewers consistently describe this as the Li-Ning No 1 Boost Badminton String being “a bit softer compared to the first generation” — a distinction that makes the Boost immediately more comfortable for players stepping up from mid-tier strings. For players whose natural preference is softer feel (Yonex BG66 Ultimax users, for example), the Li-Ning No 1 Boost Badminton String is the appropriate entry into the No. 1 family rather than the original.
• The durability improvement is the other compelling reason to choose the Li-Ning No 1 Boost Badminton String. The nano-braided core resists internal fibre slippage better than standard multifilament braiding. The elastic resin coating acts as an abrasion buffer at the string notch points where cross strings intersect — the location where most badminton strings break first. Together, these two construction elements extend the Boost’s service life beyond the original No. 1 at comparable gauge, making it the better choice for players who restring every 3–5 weeks rather than every 1–2 weeks.
• Li-Ning’s own rating of 10/10 for repulsion power on the Li-Ning No 1 Boost Badminton String — its highest repulsion rating — reflects the elastic resin coating’s contribution to the string bed’s spring-back energy. The coating provides an additional elastic layer on top of the multifilament core’s inherent stretch: contact deforms the resin coating as well as the nylon core, and both spring back to propel the shuttle. This additive elasticity is why the Li-Ning No 1 Boost Badminton String can claim equal or better repulsion than the original despite being marginally thicker at 0.66mm.

String Character Breakdown of Li-Ning No 1 Boost Badminton String:

• Gauge — 0.66mm (Thin-Performance): 0.66mm Gauge of Li-Ning No 1 Boost Badminton String is marginally thicker than the original No. 1’s 0.65mm — a 0.01mm difference that is imperceptible to the naked eye but contributes measurably to durability. At 0.66mm, the Boost still delivers high repulsion performance from a performance-tier thin string while having fractionally more material per fibre than the 0.65mm original. The elastic resin coating compensates for any repulsion reduction from the extra gauge, maintaining maximum repulsion ratings.
• Core — Heat Resistant High-Intensity Nano Braided Multifilament: The nano-braided core is the first construction upgrade from the original No. 1’s standard multifilament core. Nanotechnology in the braiding process creates microscopically tighter fibre interweaving — more contact points between filaments, better resistance to internal fibre slippage, and more consistent energy transfer on each impact. The heat resistance specification ensures performance stability during extended play sessions.
• Outer — Heat Resistant High-Intensity Nylon: Li-Ning No 1 Boost Badminton String is made with same outer material as the original No. 1 — high-intensity heat-resistant nylon providing structural integrity and consistent tension distribution across the racket frame. The outer layer in the Boost is the foundation for the elastic resin coating applied on top.
• Compound Elastic Resin Coating — The Defining Boost Upgrade: The third layer that distinguishes the Boost from the original No. 1. This polymer coating is applied over the nylon outer to provide three specific benefits: softened feel on contact (the resin cushions the shuttle-string interface compared to bare nylon), improved abrasion resistance at cross-string notch points (extending lifespan), and additive elastic spring-back (the resin coating contributes to the string bed’s total elastic response, enabling equal or higher repulsion despite the 0.01mm gauge increase). The elastic resin coating is the most significant single construction difference in the No. 1 family.
• 3D Knit Technology — Durability Foundation: The same 3D Knit braiding process as the original No. 1 — three-dimensional filament interlocking that distributes impact stress more evenly across the string’s cross-section. In the Boost, 3D Knit works alongside the nano-braided core and elastic resin coating to provide multiple layers of durability enhancement simultaneously.
• Feel — Medium-Soft: The elastic resin coating shifts the Boost’s contact feel from the original’s hard profile to medium-soft — the shuttle still departs the string bed quickly and decisively, but the initial contact is cushioned and slightly more elastic than bare nylon. The acoustic response remains clear and satisfying, with a slightly warmer tone than the original’s sharper crack. This feel profile is more accessible to a wider range of players than the original’s hard feel.

Performance Ratings — Li-Ning No 1 Boost Badminton String:

Tension Guide for Li-Ning No 1 Boost Badminton String — Indian Courts:

• Club and Recreational Play — 22–25 lbs: The most comfortable and accessible tension for the Li-Ning No 1 Boost Badminton String. At this range, the elastic resin coating’s spring-back effect is strongest — maximum repulsion with the largest sweet spot. Good for players who want the No. 1 Boost’s repulsion credentials without the precision demand of higher tension. The softer feel at this range is particularly forgiving for intermediate players.
• Competitive Club Play — 25–27 lbs: Expert reviewers consistently identify 25–27 lbs as the sweet spot for the No. 1 Boost — the tension range where repulsion and control are most balanced and the elastic resin coating provides optimal feel. The string sounds its best here: clear, decisive, with a satisfying crispness that is slightly warmer-toned than the original No. 1 at equivalent tension.
• Advanced Competitive Play — 27–29 lbs: The tension range for advanced competitive players who want the Boost’s better durability and softer feel while maintaining high-level control precision. At 27–29 lbs, the sweet spot narrows but the elastic resin coating continues to provide enough cushion to make the Li-Ning No 1 Boost Badminton String more comfortable at this tension than the original No. 1.
• Maximum Tension — 30 lbs: Do not exceed 30 lbs. The 0.66mm gauge requires tension discipline. Always verify racket tension ceiling before stringing.
• India-Specific Note: The Boost performs very well in India’s warm, humid conditions. The elastic resin coating maintains its elasticity well in warm, moist air — string performance is more consistent between cool air-conditioned halls and warm coastal courts than bare nylon strings, which become slightly stiffer in cool, dry conditions.

String Finder — Is Li-Ning No 1 Boost Badminton String Right for You?

• Intermediate Player Stepping Up From Thick Strings (BG65, No. 7): The Li-Ning No 1 Boost Badminton String is the ideal entry point into the Li-Ning No. 1 performance family for players coming from 0.70mm territory. Its softer feel is less of a shock than the original No. 1’s hard profile, and its better durability means fewer surprised early breakages during the adjustment period.
• Player Who Uses BG66 Ultimax and Wants Something More Durable: The Boost’s elastic resin coating and nano-braided core give it meaningfully better durability than BG66 Ultimax. The feel is slightly softer than the original No. 1 but maintains the elastic, lively response that BG66 Ultimax players typically prefer. A natural upgrade for BG66 Ultimax users who want better string lifespan at comparable repulsion.
• Doubles Player Who Wants Repulsion with Accessible Feel: The Boost’s softer contact and elastic response suit doubles play better than the original No. 1’s hard profile. Net touch, quick exchange repulsion, and softer feel on defensive lifts all benefit from the elastic resin coating in fast doubles situations.
• Player Choosing Between No. 1 Boost and original No. 1: Hard feel and maximum tension retention priority → original No. 1. Softer feel, better durability, and maximum repulsion rating → Li-Ning No 1 Boost Badminton String. The Boost is the right default choice for most Indian intermediate players; the original No. 1 is for players who specifically want hard feel.

Playing Style Guide for Li-Ning No 1 Boost Badminton String:

• Power / Smash-First Players:

  • Ideal Match. 10/10 repulsion rating with elastic resin spring-back — maximum shuttle speed on smashes and drives. Softer feel than the original No. 1 means smash sessions are more comfortable over extended training. String at 25–27 lbs for the best smash power and control balance.

• Control / Placement Players:
