Specialized S-works Tarmac SL8 Sram Red Axs 2025 (pre-order now)

Nothing 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, it's more than the fastest Tarmac ever - it's the world's fastest race bike. Your legs up for it?
Aerodynamics or lightweight alone don't win races - speed is what matters. Delivering that speed requires creating an uncompromising combination of aerodynamics, lightweight, stiffness, and compliance. Through race simulations using real world data our Ride Science team knows the Tarmac SL8 is the fastest race bike ever made on the routes that matter - 16.6 seconds faster over 40km, 128 seconds faster over Milan San Remo, 20 seconds faster over the legendary Tourmalet climb.
Now, the fastest race bike in the world meets SRAM RED AXS groupset with power meter - the lightest electronic groupset ever - and a Roval Rapide CLX II tubeless-ready wheelset. All S-Works Tarmac SL8 models ship with a Roval Rapide cockpit to save weight and for the fastest possible leading edge.
