The S-Works Tarmac SL8 is unbeatable in speed. Advanced aerodynamics and lightweight construction create a ride quality that once seemed unattainable. After eight generations and more than twenty years of development, it’s not just the fastest Tarmac ever – it’s the fastest road bike in the world. Are you ready? Aerodynamics and low weight alone don't determine race outcomes – what matters at the finish line is speed. Achieving race speed requires a specific balance of aerodynamics, lightness, stiffness, and compliance. Our Ride Science Team has determined through racing simulations based on real data that the Tarmac SL8 is the fastest road bike ever made on key segments. It is a full 16.6 seconds faster over 40 km, 128 seconds faster at Milano–Sanremo, and 20 seconds faster 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-light Roval Rapide cockpit – a sharp design for razor-thin victories.
