The S-Works Tarmac SL8 is unbeatable in speed. Its advanced aerodynamics and lightweight design create a riding experience that once seemed unattainable. After eight generations and over twenty years of development, it is not just the fastest Tarmac ever made – it is the fastest road bike in the world. Are you ready? Aerodynamics and low weight alone do not win races; 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 determined through race simulations based on real-world data that the Tarmac SL8 is the fastest road bike ever built on key segments. It is 16.6 seconds quicker over 40 kilometers, 128 seconds faster in Milano–Sanremo, and 20 seconds speedier on the Tourmalet. The fastest road bike in the world is now paired with the SRAM RED AXS complete group featuring power measurement – the lightest electronic group ever – and a tubeless-ready Roval Rapide CLX II wheelset. All S-Works Tarmac SL8 models come equipped with an ultra-lightweight Roval Rapide cockpit – a sharp design for razor-thin victories.
