*FEA(Finite Element Analysis)

*Techonology:

-1) Reinforcement Technology
DK Composite use reinforcement/thicker carbon fiber on each spoke hole area, and use thinner carbon fiber outside the spoke hole area, so the rim light can be saved greatly while strength can be guaranteed.

-2) Unique Resin and Lamination System

DK Composite developed own high TG 255℃ and high tenacity resin system and special lamination for best carbon bicycle rim performance.

-3)Six-Axis Drilling Machine

DK Composite developed a six-axis machine especiall for carbon bicycle rim, so all kind of angles and diameters drilling are available.

-4) Strong R&D Team

DK Composite have own R&D team for new project and mould development, except carbon bicycle rim, we also have the experiences and ability to develop any new carbon composite products.
