SPECIALIZED TARMAC SL8 EXPERT BIKE 2025

No bike is as fast as the Tarmac SL8, thanks to a combination of aerodynamics, lightness, and ride quality that was previously thought impossible. After eight generations and over two decades of development, it’s not just the fastest Tarmac ever: it’s the fastest road bike in the world. Are your legs ready?

Aerodynamics or lightness alone don’t win races: what matters is speed. To achieve this speed, we created an uncompromising combination of aerodynamics, lightness, stiffness, and compliance. Through advanced simulations using real-world data, our Ride Science Team confirmed that the Tarmac SL8 is the fastest road bike on any course: 16.6 seconds saved over 40 km of flat terrain, 128 seconds faster on the Milan-Sanremo course, and 20 seconds faster on the Tourmalet climb.

SPECIALIZED TARMAC SL8 EXPERT BIKE 2025 KEY FEATURES:

• AERODYNAMICS: We optimize aerodynamics where it matters most, creating our fastest road bike ever – yes, even more aerodynamic than the Venge. The front end has been refined to maximize advantage. The fork steerer is positioned behind the front of the head tube to offer much lower aerodynamic drag. Thanks to new UCI regulations, we’ve used the narrowest and most aerodynamic seatpost we’ve ever made, allowing turbulent air around the legs to flow more smoothly to the rear of the bike.
• LIGHTWEIGHT: To create the Tarmac SL8 as the most aerodynamic bike while meeting UCI minimum weight requirements, we applied lessons learned from the Aethos. The team designed a 685-gram frame, 15% lighter than the Tarmac SL7 and lighter than any other World Tour bike*. By focusing on minimizing weight in the down tube, seat tube, and rear triangle, we utilized insights from the Aethos project. The frame shapes are so efficient at handling loads that we reduced material thickness and eliminated excess. *Except for that one time Kasper Asgreen raced with our 585-gram Aethos frame in a Tour stage.
• RIDE QUALITY: The stiffness-to-weight ratio of the Tarmac SL8 is 33% better than the SL7. The Tarmac SL8 sets a new benchmark for handling: it’s precise in the most demanding situations and responds instantly and efficiently to pedal input. While power transfer and steering precision areas are stiffer than ever, the Tarmac SL8 is also more comfortable, absorbing 6% more road vibrations, giving a feeling of agility and balance unparalleled in the world of road bikes. The new Tarmac SL8 retains the proven geometry of the SL7, with generous clearance for 32mm tires, allowing for higher-volume tires when needed.
• BEYOND GENDER DIFFERENCES: In reality, there can be more differences between two male cyclists than between a man and a woman. We design for the individual, and our philosophy is simple: don’t create differences where they don’t exist. Every cyclist, male or female, can enjoy the benefits of the Tarmac SL8. It’s time to move beyond.
• The Tarmac SL8 Expert features the SRAM Rival eTap AXS group with a powermeter, C38 carbon tubeless-ready wheels, an SL7 stem, and a Specialized Expert alloy handlebar, offering an excellent value for money package.
