PRODUCT SPECIFICATION Weight / Grip Size 4U / G5 String tension LBS 3U:≦ 29 lbs(13Kg) 4U:≦ 28 lbs(12.5Kg) Frame Material High Resilience Modulus Graphite + HARD CORED TECHNOLOGY Shaft Material High Resilience Modulus Graphite + 6.8 SHAFT PRODUCT TECHNOLOGY Sonic Rebound Technology The Sonic Rebound Technology integrates Rebound Transition Construction and a high-resilience carbon fibre material, maximizing the rebound effect upon impact to help you strike with that extra speed like you never experienced before. Hard-Cored Technology Inspired by military helicopter, multi-layered structure made by carbon fiber and composites, minimize material size, reinforce handling feel and performance at a critical standard. SeventySix-76 The single-pass grommet hole construction creates less friction between strings, this effectively reduces tension loss, while extending string life. WES The Whipping Enhancement System incorporates a softer material in a specific part of the shaft near the throat, enhancing racket-head acceleration in a "whipping" style which helps to create steeper and quicker attacks with satisfying control. Hybrid-ON Configure and combine white wood, carbon fibre, and resin through foam moulding technique, creating a standardized design. This newly developed material can effectively increase precision, weight and performance without the tendency to absorb water and deform, enabling better hitting experience and stability. Compound-Sword Compound-Sword frame increases speed and stability. The upper part of the frame reduces air resistance, the middle part improve the energy transfer user's swing to the shuttle, and the lower part increases stability and speed by drastically reducing any racket twisting. This ensures to get as much speed for the drop shots and defences, while also giving the stability to hit accurate smashes.
