The Specialized Tarmac SL8 is unbeatable in speed. Its advanced aerodynamics and lightweight design provide a ride quality that once seemed unattainable. After eight generations and over twenty years of development, it is not only the fastest Tarmac ever created – it is the fastest road bike in the world. Are you ready? Aerodynamics and low weight alone do not decide races – at the finish line, it's all about speed. Achieving race-speed requires a specific balance of aerodynamics, lightness, stiffness, and compliance. The Specialized Ride Science Team has determined through race simulations based on real data that the Tarmac SL8 is the fastest road bike ever built on critical routes. It’s a remarkable 16.6 seconds faster over 40 km, 128 seconds quicker in the Milano–Sanremo, and 20 seconds swifter on the Tourmalet. Featuring a 68 mm wide threaded bottom bracket, flat mount for disc brakes, an incredibly lightweight frame weighing only 685g, and seamless integration, the S-Works Tarmac SL8 frame set is the perfect foundation for your dream build.
