How to choose a carbon fiber frame

Choosing a carbon fiber frame requires comprehensive consideration of material characteristics and riding needs. Carbon fiber materials are known for their lightweight (density 1.5-2.0g/cm ³) and high strength (tensile modulus 200-500GPa), but it should be noted that different manufacturing processes (such as compression molding/winding molding) can significantly affect the frame stiffness (lateral stiffness ≥ 80N/mm) and vertical elasticity (key comfort indicators). It is recommended to prioritize carbon cloth laminated frames above T700 level, which have better impact resistance (drop hammer test ≥ 15J) and weight (800-1200g). The frame size needs to match the height (with an error of ± 2cm in riser length) and riding posture (with a stack/reach ratio of 1.5:1 as the competition standard).
