S-Works Tarmac SL8 - SRAM RED AXS
Made to race
Nothing is faster than the Tarmac SL8 — a combination of aerodynamics, low weight, and ride quality previously thought impossible. After eight generations and over two decades of development, it's more than the fastest Tarmac ever: it's the world's fastest race bike, made even faster with the aero paradigm-shifting performance of the all-new Roval Rapide CLX III wheels.
Best for: Road racing, fast group rides and performance-focused training.
