The S-Works Tarmac SL8 is unbeatable in speed. Its advanced aerodynamics and low weight create a riding experience that seemed unattainable. After eight generations and more than twenty years of development, it is not only the fastest Tarmac ever made – it is the fastest road bike in the world. Are you ready? Aerodynamics and low weight alone do not decide races – what matters at the finish line is speed. Achieving race speed requires a precise balance of aerodynamics, lightness, stiffness, and compliance. Our Ride Science Team has discovered through race simulations using real-world data that the Tarmac SL8 is the fastest road bike ever built on key segments: it is 16.6 seconds faster over 40 km, 128 seconds quicker on the Milano–Sanremo, and 20 seconds ahead on the Tourmalet. The world's fastest road bike now features the SRAM RED AXS complete group with 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 – razor-sharp design for razor-thin victories.
