ECHO Aero Frame – Engineered for Speed
Core Technical Philosophy：
Based on the Kammtail tube profiling theory, optimized for specific frame zones
Validated with Computational Fluid Dynamics (CFD) and Finite Element Analysis (FEA)
Design motto: Fast, faster – so fast only the echo remains.
Aerodynamic Optimization
Differentiated Tube Profiling:
Top tube and seat tube use highly aerodynamic shapes – airflow accelerates between the legs, where drag matters most
Down tube prioritizes structural efficiency – aerodynamic gains are limited in the front wheel wake.
