The Tarmac SL8 isn’t just fast—it’s the fastest race bike in the world, thanks to a groundbreaking mix of aerodynamics, lightweight design, and ride quality that was once thought impossible. After over two decades and eight generations of development, it’s more than the fastest Tarmac ever—it’s a whole new level of speed. Ready to put your legs to the test?
Speed isn’t just about aerodynamics or lightweight design alone—it’s about a perfect balance of all the key elements. To achieve that, we’ve combined aerodynamics, lightweight construction, stiffness, and compliance in an uncompromising way. Our Ride Science team, using real-world race simulations, confirms the Tarmac SL8 is the fastest race bike ever over the courses that matter: 16.6 seconds faster over 40km, 128 seconds faster over Milan-San Remo, and 20 seconds faster on the legendary Tourmalet climb.
AERO IN EVERYTHING: We’re putting aerodynamics where it counts most—on the leading edge. This results in our most aerodynamic road bike ever, even more aero than the Venge. The new Speed Sniffer nose cone optimises airflow, and by moving the steer tube back, we’ve made the head tube more aerodynamically efficient. Plus, the Tarmac SL8 features the narrowest and most aero seat post we’ve ever designed, reducing drag around the legs for cleaner airflow. Victory has never smelled so sweet.
MINIMUM WEIGHT, MAXIMUM AERO: Thanks to insights from the Aethos, the Tarmac SL8 is designed to hit the UCI’s minimum weight limit while still achieving a fully aero setup. The result is a frame that tips the scales at an astonishing 685 grams—15% lighter than the Tarmac SL7 and the lightest on the World Tour*. By applying lessons from the Aethos, the design focuses on weight savings in the down tube, seat tube, and rear section, allowing us to eliminate unnecessary carbon layers without sacrificing performance. (*Unless you count Kasper Asgreen's 585g Aethos frame during a Tour stage.)
GOES LIKE HELL, RIDES LIKE HEAVEN: The Tarmac SL8 offers a 33% improvement in stiffness-to-weight over the SL7, pushing legendary handling, responsive performance, and World Championship geometry to new heights. It’s stiffer at the pedals, more precise at the handlebars, and combines all of that with a ride quality that sets a new standard for comfort in race bikes. Thanks to Rider-First Engineering, every rider, regardless of size, gets the same exceptional ride quality and handling. The Tarmac SL8 also delivers 6% more compliance, offering a smoother, more supple ride over rough roads. Its proven geometry and 32mm tire clearance are unchanged from the SL7, ensuring easy adaptation and versatility for larger tires when needed.
BEYOND GENDER: Gender doesn’t determine how a rider experiences a bike, and it certainly doesn’t provide enough data to design gender-specific bikes. That’s why we’ve created the Tarmac SL8 to offer the same top-tier performance for every rider. It’s time to go Beyond Gender.
The S-Works Tarmac SL8 is equipped with the finest components, including a full Shimano Dura-Ace 9200 series Di2 groupset with dual-sided power meter and a Roval Rapide CLX II tubeless-ready wheelset. The world’s fastest frame is paired with the best to ensure optimal performance. All S-Works Tarmac SL8 models come with a Roval Rapide cockpit, designed to save weight and provide the fastest possible leading edge.

Cycle to Work Scheme: Affordable Riding for UK Employees
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.
The process is seamless: Choose the bike that suits your needs and budget from our extensive range. Your employer will then set up a salary sacrifice arrangement, spreading the cost of your bike over a specified period, typically 12 to 18 months.
Once the salary sacrifice period ends, you have the option to own the bike outright for a nominal fee, ensuring you get to keep and enjoy your trusted two-wheeled companion for years to come.
Experience the freedom of cycling, save money, and reduce your carbon footprint with the Cycle to Work Scheme. Join countless UK employees who have already embraced this eco-friendly and wallet-friendly way of commuting.
