Core Shell Rubber(C.S.R)

Core shell rubber is used to cover the epoxy resins to build resilience and protection. Core shell rubber is added into carbon fiber and the foam materials used to fill the frame, which not only increases the extension strength of carbon fiber, but also improves the resilience. The Foamex turns much more compacted during the foaming process, and possesses with better shock absorption once the foaming is done.

Continuation Grommet

Takes up the wind and increase the swing speed, and prevent the frame from damaging by the strings while in high stringing tension.

Power Box

The box-shaped design effectively increases the stability and anti-torque, can stand higher string tension. 

Internal T-Joint

One-piece T-Joint (compare to the external T-joint), transfer the power smoothly, and precise the hit.

Seven-Six76

The single-pass grommet hole construction creates less friction between strings, this effectively reduces tension loss, while extending string life.
