    AERO IN EVERYTHING

    Our Most Aero Race Bike Ever

    After a decade of working in the Win Tunnel, our engineers put aero where it matters, not just where it looks good. The result? A new Nose Cone called the ‘Speed Sniffer’ helps the new Tarmac SL8 be 16.6 seconds faster over 40km than the Tarmac SL7. And yes, more aero than the Venge.

  • Specialized Tarmac SL8 and Tarmac SL7 weight comparison

    Minimum Weight, Maximum Aero

    685 Gram Frameset

    We saw how the lightest production road bike in the world - the Aethos - could marry blistering response in the mountains with a supple, all-day ride. The Tarmac SL8 took those learnings from Aethos to be easily built at the UCI minimum with a full aero set up.

    Goes Like Hell, Rides Like Heaven

    Stiffer and Smoother

    The Tarmac SL8 delivers a massive 33% improvement in stiffness to weight vs the SL7, all while being 6% smoother in the saddle. With World Championship proven geometry and 32mm tire clearance, it adds up to an unprecedented ride quality.

    The Tarmac SL 8 White Paper

    The World’s Fastest Race Bike

    Our Ride Science team tests our solutions versus the competition before a pedal is even turned. Through complex simulations of real world race routes with identical real world data, our Ride Science team knows the Tarmac SL8 is the fastest race bike ever made.

2025 Specialized S-Works Tarmac SL8 SRAM RED AXS Features

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.

  • BEYOND GENDER: There can be more difference between two male cyclists than between a male and female. Gender alone doesn’t provide nearly enough data to specialize and that means creating male or female bikes is arbitrary and outdated. Every rider can get the next level advantage of Tarmac SL8. It’s time to go Beyond Gender.
  • S-Works Tarmac SL8 is spec’d with only the best components. A full SRAM RED AXS groupset with power meter - the lightest electronic groupset ever - and a Roval Rapide CLX II tubeless-ready wheelset are the perfect complement to the world’s fastest frame. All S-Works Tarmac SL8 models ship with a Roval Rapide cockpit to save weight and for the fastest possible leading edge.
