The S-Works Tarmac SL8 is unbeatable in speed. Its advanced aerodynamics and lightweight construction result in a ride quality that once seemed unattainable. After eight generations and more than twenty years of development, it is not just the fastest Tarmac ever created – it is the fastest racing bike in the world. Are you ready? Aerodynamics and low weight alone do not win races – it’s all about speed when you cross the finish line. Achieving race speed requires a precise balance of aerodynamics, weight, stiffness, and compliance. Our Ride Science Team has conducted race simulations based on real data, discovering that the Tarmac SL8 is the fastest racing bike ever built on key routes. It is 16.6 seconds faster over 40 km, 128 seconds faster in the Milano–Sanremo, and 20 seconds faster on the Tourmalet. The world's fastest racing bike now pairs with the SRAM RED AXS groupset featuring power measurement – the lightest electronic groupset ever – and a tubeless-ready Roval Rapide CLX II wheelset. All S-Works Tarmac SL8 models come equipped with an ultralight Roval Rapide cockpit – razor-sharp design for razor-thin victories.
