Yonex BG EXBOLT 63 10m 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. Thefirst to the series is the EXBOLT 63, and is constructed from a proprietary new materialcalled FORGED FIBER which is a first to combine durability, thin gauge and quickrepulsion all into one. The EXBOLT 63 will be available at the end of March 2021. While thinner strings tend to have higher repulsion, there has always been the issue oflow durability. FORGED FIBER was developed to solve this very issue. Ordinary nylonhad 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 thegauge 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. *1 Measured by a smash analysis machine*2 Yonex research results: Shuttle is delivered to the same location 0.18 seconds faster than compared to previous products. INNOVATIONFORGED FIBERFORGED FIBER, a new material developed from a fiber with high intermolecularbonding strength, durability, and heat resistance, which is also used in the forging ofaircraft tires. Impurities are removed during the manufacturing process, and bystretching the material many times longer than the original material, the strength of this FORGED FIBER is greatly increased.       Specification Product Exbolt 63 Description Thin and Durable Color Yellow, Black, White, Mint, Light Pink, Ruby Red Gauge 0.63 mm Length 10 m (33 ft) Core High-Intensity Nylon Multifilament Outer Special Braided Forged Fiber Made In Japan Item Code BGXB63   Yonex | badminton | strings | Exbolt | Exbolt 63 | BG Exbolt 63 | BG Exbolt | bgxb63 | yellow | black | white | 2021 | thin | durable | BGXB63 | BGEXB6310
