This is a 56cm Cannondale SuperSix Evo carbon fiber road bike. The frame was originally the SRAM RED build, but was swapped over to Ultegra 6800 11 speed. Has 172.5mm FSA SLK 52/36t carbon cranks, recent Supacaz tape, Pinarello Most bars, and a set of light and fast Giant P-SL0 wheels with DT Swiss 350 Tricon straight pull hubs with star ratchets. 16.8lbs on my bathroom scale.
