Tarmac SL8: The Fastest Race Bike in the World

The Tarmac SL8 isn't just the fastest Tarmac ever made—it's the fastest race bike in the world. After more than two decades and eight generations of relentless innovation, we’ve created a bike that pushes the boundaries of aerodynamics, lightweight design, and ride quality in ways that were once thought impossible. Ready to take on the world’s fastest race bike?

Speed Is Everything

Aerodynamics and lightweight alone won’t win you the race—speed does. And achieving that speed means blending aero performance, lightweight design, stiffness, and compliance into one seamless machine. Our Ride Science team used real-world data to prove that the Tarmac SL8 is the fastest race bike ever built. It’s:

  • 16.6 seconds faster over 40km
  • 128 seconds faster over Milan-San Remo
  • 20 seconds faster on the legendary Tourmalet climb

Aero Performance in Every Detail

We’ve taken aero to new heights by focusing on what matters most: the leading edge. The Tarmac SL8 is our most aerodynamic road bike ever—more so than the Venge. The new Speed Sniffer nose cone optimises airflow to give you every aerodynamic advantage. We’ve also repositioned the steer tube to create a sharper, more efficient head tube shape, reducing drag significantly. And following updated UCI rules, the Tarmac SL8 features the narrowest, most aero seat post we’ve ever designed, helping clean air flow around the legs for maximum efficiency. Victory is in the air.

Minimal Weight, Maximum Aero

The Tarmac SL8 takes full advantage of Aethos-inspired lightweight construction to meet the UCI minimum weight with an aero-focused setup. We’ve achieved a mind-blowing 685g frame15% lighter than the Tarmac SL7 and the lightest frame on the World Tour. By applying lessons from Aethos, we’ve refined the down tube, seat tube, and rear triangle to be as lightweight as possible without sacrificing performance. The frame’s shape carries loads so efficiently that extra carbon stiffness layers become unnecessary. (And yes, we’re still talking about the 585g Aethos frame Kasper Asgreen raced on during a Tour stage.)

Unmatched Performance and Comfort

With a 33% increase in stiffness-to-weight over the SL7, the Tarmac SL8 offers a new level of handling, responsiveness, and comfort. The bike is stiffer at the pedals, more precise at the bars, and provides a smoother, more compliant ride in the saddle. Thanks to Rider-First Engineering, every rider gets the same unrivalled ride quality, regardless of size. The Tarmac SL8 offers 6% more compliance, helping you float over rough roads with a smooth, supple feel that’s unheard of in the world of race bikes. Plus, it keeps the Tarmac geometry and 32mm tire clearance of the SL7, ensuring you can adapt easily and run higher-volume tires when you need extra comfort or grip.

Beyond Gender

Gender doesn’t determine how you ride. In fact, two male riders can vary more than a male and female rider. It’s time to leave behind the outdated idea of gender-specific bikes. The Tarmac SL8 is built to give every rider the same performance advantage, regardless of gender. Go Beyond Gender and experience the Tarmac’s next-level performance.

Unlock a cost-effective way to own the bike of your dreams through the Cycle to Work Scheme. This initiative, available to employees in the UK, lets you enjoy the benefits of cycling while saving on your bike purchase.

With the Cycle to Work Scheme, you can use your pre-tax salary to acquire a brand-new bicycle and essential cycling accessories. This means significant savings for you, as your salary sacrifice reduces both your income tax and National Insurance contributions.
