Specialized S-Works Shiv TT: for years, chrono bikes have been designed in a very similar way, flat and aerodynamic piping, heavy and difficult to ride frames, often rough braking. For flat, fast routes, as was once the custom, these features might perhaps be fine. With today's technically very challenging tracks, however, time trial bikes must be different. Shiv TT moves towards the limits of the UCI regulation by adding disc brakes, filing weight and refining the position.
