YONEX Skyarc Badminton String


Exbolt 63: The first addition to the new string series / Thin gauge string with higher durability!

TOKYO, Japan – Introducing a brand-new badminton string series, the EXBOLT. The
first to the series is the EXBOLT 63, and is constructed from a proprietary new material
called FORGED FIBER which is a first to combine durability, thin gauge and quick
repulsion all into one. 

While thinner strings tend to have higher repulsion, there has always been the issue of
low durability. FORGED FIBER was developed to solve this very issue. Ordinary nylon
had a limit to the strength of its fibers, which is why Yonex reconstructed the fibers on a molecular level to build stronger bonds for lasting durability. This FORGED FIBER gave Yonex more freedom to construct thinner strings without compromising durability.

The result is a combination of quick repulsion and durability, and even though the
gauge is only 0.63mm, it is 24% more durable than conventional thin gauge products*1.  The EXBOLT 63 provides exhilarating sounds of impact, and its quick repulsion will deliver your drives 7cm deeper*2, giving the opponent little to no time to counterattack or gain the upper hand in a match.

FORGED FIBER, a new material developed from a fiber with high intermolecular
bonding strength, durability, and heat resistance, which is also used in the forging of
aircraft tires. Impurities are removed during the manufacturing process, and by
stretching the material many times longer than the original material, the strength of this FORGED FIBER is greatly increased.
