TT03 Disk
The blade runner. Maximum aerodynamics, minimum compromise.
The De Rosa TT Disc is the result of intense research and development aimed at three clear objectives: maximum aerodynamics, reduced weight, and greater stiffness. A minimalist frame — a real blade forged to slice the wind.

The TT03 Disk embodies the result of intense research and development by De Rosa, aimed at three clear objectives: maximum aerodynamics, reduced weight, and greater stiffness. Starting with the head tube — perfectly integrated with the handlebar and featuring completely internal cable routing — every surface has been optimised. The continuous curvature of the vertical tube integrates seamlessly with the seat stay and bottom bracket shell. This is the state of the art in aerodynamic engineering, forged in Milan.
