The S-Works Tarmac SL8 is unbeatable in speed. Its advanced aerodynamics and lightweight design deliver an unparalleled riding experience that once seemed unattainable. After eight generations and over twenty years of development, it's not only the fastest Tarmac ever made but also the fastest road bike in the world. Are you ready? Aerodynamics and low weight alone do not determine race outcomes; it's all about speed at the finish line. Achieving race speed requires a specific balance of aerodynamics, lightness, stiffness, and compliance. Our Ride Science Team has conducted race simulations using real-world data and discovered that the Tarmac SL8 is the fastest road bike ever built over key distances. It is 16.6 seconds quicker over 40 kilometers, 128 seconds faster in the Milano–Sanremo, and 20 seconds swifter on the Tourmalet. The world's fastest road bike now pairs with the SRAM RED AXS complete group featuring power measurement—the lightest electronic group ever made—and a tubeless-ready Roval Rapide CLX II wheelset. All S-Works Tarmac SL8 models come equipped with an ultra-lightweight Roval Rapide cockpit—engineered for razor-sharp performances and victories.
