Wiel Carbon Road/racing Bike Frame & Full Carbon Fibre&matte black&red 520mm B111 Double-molding technology make the inside carbon wall smooth. Through controlling carbon fiber accurately and optimizing process, carbon fiber can be overlap joint casualy to solve the problem of inequality and irregularity. With these advantages, inner wall without bend and yarn break. More safe and comfortable during riding. Technologically superior monocoque frame building processes and thick-wall, high vacuum forming machines allow WEDO the control over the shape and the ability to make a better rigidity and strength. EPS core mold and air bags cost is lower than others. Air bag outside the EPS core mold can working as airproofing, and avoid the EPS toughing carbon fiber. This process is easy for moulding, contractibility is small,and its easy to take it out. We use Automatic wrapping technology to make product stronger and safer and the performance reach 95%.
