The S-Works Tarmac SL8 is unbeatable in speed. Its advanced aerodynamics and lightweight design deliver a ride quality that once seemed unattainable. After eight generations and more than twenty years of development, it is not only the fastest Tarmac ever created – it's the fastest road bike in the world. Are you ready? However, aerodynamics and low weight alone do not determine race outcomes – what matters at the finish line is speed. Achieving race speed requires a very specific balance of aerodynamics, lightness, stiffness, and compliance. Our Ride Science team has discovered through racing simulations based on real data that the Tarmac SL8 is the fastest road bike ever built on crucial segments: it is 16.6 seconds faster over 40 km, 128 seconds quicker at Milano–Sanremo, and 20 seconds faster on the Tourmalet. The fastest road bike in the world now incorporates the SRAM RED AXS groupset with power meter – the lightest electronic groupset ever – along with a tubeless-ready Roval Rapide CLX II wheelset. All S-Works Tarmac SL8 models are equipped with an ultra-lightweight Roval Rapide cockpit – streamlined design for razor-thin victories.
