⚡ At a Glance
  • Repulsion and Durability: Enhanced repulsion combined with up to 24% more durability and a crisp hitting sound
  • Best for: Club-level players and attacking players who want lively strings that last
  • Not ideal for: Players who prefer very soft, plush string tension and maximum dwell time

Forged Fibre construction with a 0.63mm gauge in a 10m length. Designed to boost repulsion while improving durability and delivering a clear audible hit.


Higher repulsion and faster shuttle response - with Forged Fibre construction

Forged Fibre manufacturing removes impurities and raises intermolecular bonding, creating stronger polymer chains that stretch and rebound efficiently. The higher bonding force helps the string return energy quickly on impact.

Stronger rebound produces livelier clears and faster shuttle movement, useful for players who favour attacking shots and rapid court coverage.

Longer lifespan between restring sessions - thanks to enhanced durability

High intermolecular bonding increases tensile strength and reduces weak points during manufacture, a process that Yonex says yields up to 24% more durability. The construction resists wear from repeated impacts.

Reduced restring frequency for players who train often, delivering better uptime and a more consistent string bed across multiple sessions.

Comfortable feel and clear feedback on contact - with 0.63mm gauge and resilient build

A 0.63mm gauge offers a slightly firmer profile while the resilient fibre composition smooths impact and transmits a distinct hitting sound. The combination balances touch with responsiveness.

Players receive precise tactile cues and audible feedback that help judge shot quality without feeling harsh during extended play.
