best fit carbon

Assuming you are a professional cyclist who descends high risk downhill on traffic blocked roads you may need an extremely aerodynamic position. But most probably you are having different needs. Then you may use more spacers to bring your stem up a bit or get a bigger frame. It may be good enough but it is not best fit.

Most high end carbon frames are built with best carbon fiber from aerospace industry. Aerodynamic, balanced for stiffness and comfort. A must every frame builder has to offer today. But one thing most manufacturers don’t like to talk about. The big advantage of a custom built frame got completely sacrificed by monocoque mass production.
