Specialized has unveiled the S-Works Tarmac SL9, the newest generation of its premier road racing bicycle. The company claims that this design is its fastest model to date when evaluated under real-world racing conditions.
With the development of the S-Works Tarmac SL9 bike, Specialized departed from the conventional approach of optimizing isolated factors such as aerodynamics or weight and instead focused on a holistic performance metric termed 'Time to Finish.' This approach innovates by accounting for the variable demands of actual race courses. Through its proprietary Equation of Speed methodology, Specialized employed simulations that incorporate rider power output, terrain profiles, and aerodynamic drag to validate the premier road racing bicycle's performance across authentic World Tour stages. The frame weighs a reported 687 grams, and complete builds are said to start at approximately 6.5 kilograms.
