Mtb Hybrid Road Bike Carbon Gravel Bike With Shimano 4700-20 Speed 40C Tire
TWITTER Bike has launched carbon fiber frames which made of EPS technology－ EPS means Ethyl Poly Styrene
The mandrel made of a thermoplastic material made of polystyrene compound conforming to the inner diameter of the frame is used as the basis for the production of the frame. If the stability of the overall quality of the frame can be enhanced, the internal wrinkles are prevented to increase the rigidity. In the market's pursuit of a highly rigid ultra-light carbon frame, this technology can greatly extend the life of the carbon frame and improve its safety. In the production process, the carbon fiber layer is coated on the EPS, and the mandrel is pulled out after being stabilized by molding. If the technology of TPM (thermoplastic layer technology) can be further combined, the ultra-light frame can be maximized. Good security effect.

Adantages of Carbon Fiber Road Bike
1. Strong carbon fiber shell durable frame, strong and light weight.
2. The finished frame has better hardness, toughness, strength to weight ratio tightness and other qualities.
3. Significantly improve the stability and smoothness of the lamination and joint between the inner cavity of the frame.
4. Greatly reduce the excessive concentration of internal stress of the frame, the length of the finished frame life, stable quality
5. The finished frame has a smooth appearance.
