S-Works Tarmac SL8 AXSNothing is faster than the Tarmac SL8 thanks to a combination of aerodynamics, lightweight, and ride quality previously thought impossible. After eight generations and over two decades of development, its more than the fastest Tarmac ever. Its the worlds fastest race bike made even faster with the aero paradigm shifting performance of the all new Roval Rapide CLX III wheels. Aerodynamics or lightweight alone dont win races speed is what matters.
