The De Rosa TT Disc embodiesthe result of intense research and development work by De-Rosa, aimed toachieve 3 clear objectives: maximum aerodynamics, reduced weight, and greaterstiffness. Thanks to De Rosa's tradition in racing frame construction and theexperience gained through years of close collaboration with cutting-edge designstudios, all angular surfaces have been eliminated. Clearly evident on the restof the frame is the hard work of optimizing the profiles. Starting with thehead tube, perfectly integrated with the handlebar, that sports a completelyinternal cable routing, continuing with the dynamic line of the top tube andthe oblique thinning. Everything runs fast, harmoniously Maximum attention wasalso paid to the continuous curvature of the vertical tube that is perfectlyintegrated with the seat stay and the bottom bracket shell: we are in the stateof the art of aerodynamic studies.
