Geometric Graph

1. Full hand-wrapped and monocoque carbon structured; 2.Using the T700 carbon fiber from Toray/Japan; 3. Moulding in one time at agglutination position so that it can obtain more capability and avoid needless broken; 4. Stairways pattern of agglutination,enlarging the agglutination surface and enhancing the agglutination basis;
5.The double-mould anti-wrinkle production technology: To use a kind of EPS foamas the inner mould---the inner mould can make a smooth surface on the inside offrame tubing----the smooth surface provides extra stability and higher production quality----higher stiffness and rigidity, less weight;
