Advanced composite technology giants high performance grade raw carbon material is used to produce this custom frame material in our own composite factory with a high stiffness to weight ratio. The front triangle of these framesets is assembled and molded as one continuous piece in a proprietary manufacturing process called modified monocoque construction. Aerosystem shaping technology through cfd computational fluid dynamics and wind tunnel data engineers optimize each tube shape to deliver superior aerodynamic performance. Overdrive aero found inside the head tube of the defy propel and tcr ranges the d shaped fork steerer tube and corresponding spacers provide an extremely aerodynamic easier to service system of internally routed brake and derailleur cables.
