The EPS-Ethyl Poly Styrene technology, or EPS-technology aid to improve the frame's safety and lifetime, creating a highly rigid ultra-light material. In this technique, the carbon fiber layer is coated on the EPS, and the mandrel is pulled out after being stabilized by molding. You can better understand the process in this video: Twitter Bike Introduction. Through this technique is possible:
Has a sturdy carbon fiber casing, making the frame durable and sturdy, and light in weight;
Has a positive strength to weight ratio, strength and shock absorption properties make it effective for the frame;
Reduce the excessive stress concentration inside the frame;
Stabilization and smoothness between the laminates in the inner layer of the frame and the joint;
The finished frame has a bright and smooth appearance.;
The finished frame has high hardness, good toughness, good strength and good adhesion, and
The finished frame has high hardness, good toughness, good strength and good adhesion, and stable quality.
